Answer in detail?? What precautions would you take to protect yourself from an earthquake, when you are at home and when you are outdoors?

Answers

Answer:

If you're indoors, stay inside. If you're outside, stay outside. If you're indoors, stand against a wall near the center of the building, stand in a doorway, or crawl under heavy furniture (a desk or table). Stay away from windows and outside doors.

Answer

Protect your head and neck with a large book, a pillow, or your arms. The goal is to prevent injuries from falling down or from objects that might fall or be thrown at you.If you are able, seek shelter under a sturdy table or desk. Stay away from outer walls, windows, fireplaces, and hanging objects.If you are unable to move from a bed or chair, protect yourself from falling objects by covering up with blankets and pillows.If you are outside, go to an open area away from trees, telephone poles, and buildings, and stay there.

Question:
Nearly the entire world uses the metric system for their measurements. The US is one in of three countries that does not use metric. Would you support changing school curriculum to teach the metric system as the primary measurement system in the US? Why or why not.
(It must be 3-5 sentences long please)

Answers

Answer:

I would

Explanation:

I would support the change to the metric system only because it allows children to understand smaller forms of units and measurements. Also, it will allow people in the math and science fields to broaden their knowledge of equations and formulas. Meaning that the scientist and mathematicians will be able to solve more problems in the world right now.  Overall, the education system for the children of the United States would benefit from the change in the measurement system.

FIRST OPTION WHICH IS A: UNIVERSAL SOLVENT

Explanation:

Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.

When a vacancy exists in an inner electron shell of an atom (as a result of photoelectric effect, Compton scattering, or bombardment by other electrons), the energy liberated when this vacancy is filled, instead of emerging from the atom as fluorescent radiation, can be transferred to another electron of the atom, thereby ejecting the electron. Such an emitted electron is called a(n) _____ electron

Answers

Answer:

The answer is "Auger".

Explanation:

The Auger effect is an effect size when the vacancy of even an atom throughout the inner shell was complemented by the release of even an electron from the same atom. Whenever a central electron is lost, a higher energy level electron can drop into the void and release energy, which can be the result.

What is the change in enthalpy of the first reaction below, given the enthalpies of the other two reactions?

Here's the reactions:

There was a formatting issue with the specific chemistry symbols, there all correct in the picture below

2C(s) + O2(g) → 2CO(g)


C(s) + O2(g) → CO2(g) ∆H0= -394 KJ/mol



CO(s) + 1/2 O2(g) → CO2(g) ∆H0= -283 KJ/mol


There was a formatting issue with the specific chemistry symbols, there all correct in the picture below

Answers

Answer:

∆H0 = -222kJ/mol

Explanation:

Using Hess's law, we can find the ΔH of a reaction from the sum of another related reactions as follows:

Using the reactions:

(1) C(s) + O2(g) → CO2(g) ∆H0= -394 KJ/mol

(2) CO(s) + 1/2 O2(g) → CO2(g) ∆H0= -283 KJ/mol

Twice (1):

2C(s) + 2O2(g) → 2CO2(g) ∆H0= 2*-394 KJ/mol = -788kJ/mol

The inverse reaction of (2):

-(2) CO2(g) → CO(g) + 1/2 O2(g) ∆H0= 283 KJ/mol

Twice this reaction:

2*-(2) 2CO2(g) → 2CO(s) + O2(g) ∆H0= 2*283 KJ/mol= 566kJ/mol

Now, the sum of 2*(1) - 2*(2) produce:

2C(s) + 2O2(g) + 2CO2(g)→ 2CO2(g) + 2CO(g) + O2(g) ∆H0= -788kJ/mol +  566kJ/mol

Subtracting the molecules that ar in both sides of the reaction:

2C(s) + O2(g) → 2CO(g) ∆H0 = -222kJ/mol

Ethylene glycol (antifreeze) has a density of 1.11 g/cm^3. What is the volume (in m^3) of 9.7 tons?(1 ton = 2.000*10^3lb; 1 kg= 2.2046 lb

Answers

Answer: The volume of 9.7 tons of given ethylene glycol is 0.0079 [tex]m^{3}[/tex].

Explanation:

Given: Density = 1.11 [tex]g/cm^{3}[/tex]

Mass = 9.7 tons

Convert tons into lb as follows.

[tex]1 ton = 2 \times 10^{3} lb\\9.7 ton = 9.7 ton \times 2 \times 10^{3} \frac{lb}{1 ton}\\= 19.4 \times 10^{3} lb[/tex]

Now, lb is converted into kg as follows.

[tex]1 kg = 2.2046 lb\\1 lb = 0.453592 kg\\19.4 \times 10^{3} lb = 19.4 \times 10^{3} lb \times 0.453592 \frac{kg}{1 lb}\\= 8.79 kg[/tex]

1 kg = 1000 g

So, 8.79 kg = 8790 g

Density is the mass of a substance divided by its volume. Hence, volume of ethylene glycol is calculated as follows.

[tex]Density = \frac{mass}{volume}\\1.11 g/cm^{3} = \frac{8790 g}{volume}\\volume = 7918.92 cm^{3} (1 cm^{3} = 10^{-6} m^{3})\\= 0.0079 m^{3}[/tex]

Thus, we can conclude that the volume of 9.7 tons of given ethylene glycol is 0.0079 [tex]m^{3}[/tex].

calculate the mass of magnesium needed to make 25g of magnesium oxide​

mark brainliest of correct xx

Answers

Answer:

15g

Explanation:

First, you need to correct the answer to the previous question. The percentage by mass of Mg in MgO =

Mg = 24.3 amu

O = 16.0 amu

The total mass of MgO = 40.3 amu

To calculate the percent composition of Mg:

% = 24.3/40.3 x 100

% = 60

To calculate the mass of Mg needed to make 25g of MgO:

x/25g = 60%/100%

100x = (25)(60)

100x = 1500

x = 15g

The air you breathe is a solution of about 78% nitrogen and 21% oxygen and 1% other
gases. Which substance is the solvent? Explain how you know

Answers

Answer:

I believe nitrogen would act as the solvent, I know this because there is a higher percentage of it than oxygen and other.

In the air composition provided, nitrogen is the solvent, while oxygen and the other gases are the solutes dissolved within the nitrogen solvent.

In a solution, the solute is the substance that is present in a smaller quantity and is dissolved in a larger quantity of another substance called the solvent. The solute may dissolve in the solvent to create a homogeneous mixture.

In the given case, air is a mixture of gases, and the major components are nitrogen (78%) and oxygen (21%), with a small percentage of other gases (1%). Here, nitrogen and oxygen are the solutes, and the remaining gases are also solutes, but in a smaller proportion.

The solvent is the component that dissolves the solute, and in the case of air, nitrogen is acting as the solvent. Nitrogen, being the most abundant gas in the mixture, forms the "base" or "carrier" for the other gases to be mixed within. Oxygen and the other gases dissolve or mix into nitrogen gas, creating a homogeneous mixture that we breathe.

Thus, in the air composition provided, nitrogen is the solvent, while oxygen and the other gases are the solutes dissolved within the nitrogen solvent.

Answer:

A

Explanation:

Hydrogen bonds are intermolecular forces of interaction that exist between molecules of a substance in which hydrogen is bonded to a highly electronegative atom. Hydrogen bonds are strong intermolecular forces and account for high melting and boiling points of small molecules such as water. They stem from dipole-dipole interaction between molecules of a substance.

Metallic bonds are bond forces which exist in a metal. Metal cations are held together by a sea of electrons via electrostatic interaction.

The ionic bond is formed by transfer of electrons from one atom to another leading to the formation of an ion pair held together by electrostatic attraction.

Metallic bonds and hydrogen bonds are much weaker than ionic bonds. Ionic compounds are known to have high melting and boiling points.

What is the expected density of the above sample of gas?
A - 3.16 g/L
B - 1.58 g/L
C - 1.21 g/L
D - 1.03 g/L

Answers

Answer:

Option A. 3.16 g/L

Explanation:

We'll begin by calculating the molar mass of Cl₂. This can be obtained as follow:

Molar mass of Cl₂ = 2 × 35.45

= 70.9 g/mol

Finally, we shall determine the density of Cl₂. This can be obtained as follow:

Molar mass of of Cl₂ (M) = 70.9 g/mol

Pressure (P) = stp = 1 atm

Temperature (T) = stp = 273 K

Gas constant (R) = 0.0821 atm.L/Kmol

Density (D) =?

D = PM / RT

D = (1 × 70.9) / (0.0821 × 273)

D = 70.9 / 22.4133

D = 3.16 g/L

Thus, the density of the gas is 3.16 g/L.
