Explanation:

because ignoring the pH solution part and doing the math it comes around to 1.0x5.0 which 1 times anything is itself so its 5

So what you dos is the final temperature - the initial temperature. For example for 1) we have 88.5 celsius degrees - 78 celsius degrees = 10.5 celsius degrees.

Answer:

O lowering the temperature of the system

a. Mg(12) 2.8.2 -2e- = Mg2+

b. S(16) 2.8.6 +2e- = S2-

c. MgS

d. No, because it is neutral

It should be noted that the maximum internal receiving temperature for fresh poultry is 41°F.

Temperature simply refers to the measure of hotness or coldness which is expressed in several scales. It's the manifestation of thermal energy in a matter.

It should be noted that the key to limiting the bacterial growth of food is to control the temperature. The maximum acceptable receiving temperature for fresh poultry is 5°C (41°F).

Answer:

A strong base has a much smaller concentration of positive ions (hydrogen ions) and a much greater concentration of negative ions (hydroxide ions). The weak base has a much greater concentration of positive ions (hydrogen ions) and a much smaller concentration of negative ions ( hydroxide ions) = answer !!

Explanation:

Answer:

Sodium and chloride form an ionic bond. Therefore the sodium atom loses one electron from its outer shell and the chlorine atom gains one electron. As this happens, the electron is transferred from the sodium atom to the chloride atom and so both atoms become ionic and have a full outer shell.

Explanation:

There are various kind of elements that are present in periodic table. Some elements are harmful, some are radioactive, some are noble gases. Therefore, the correct option is option A.

Periodic table is a table in which we find elements with properties like metals, non metals, metalloids and radioactive element arranges in increasing atomic number.

Periodic table help a scientist to know what are the different types of elements are present in periodic table so that they can discover the new elements that are not being discovered yet.

Along period, electronegativity increases. along group electronegativity decreases. The same trend is followed by  first ionization energy in periodic table.

Therefore, the correct option is option A.

Answer:

The same as on earth

Explanation:

mass is the amount of matter in an object and the mass of an object is always the same at any point in time

gravity will only have effect on the weight and not the mass.

so assuming the question was talking about the weight, then we can say the weight will be lesser on Mercury

Answer:

Hand warmers and instant cold packs use endothermic reaction that release or absorb thermal energy.

Thermal energy is defined as by virtue of its temperature, a system in a condition of thermodynamic equilibrium contains internal energy. Fossil fuels like natural gas, coal, and oil are examples of thermal energy sources. They also include solar heat, electric heat pumps, and geothermal heat. Thermal energy is a type of kinetic energy, which is energy brought on by motion, and is brought on by the motion of particles. Things have an interior temperature as a result of thermal energy, which can be detected with a thermometer.

Endothermic reaction is defined as the chemical processes that result in the formation of products when the reactants absorb heat energy from their surroundings. A chemical reaction or physical change is referred to as being endothermic when heat is absorbed by the system from the environment. An endothermic process causes the system to absorb heat from its surroundings, which causes the surroundings' temperature to drop.

Thus, hand warmers and instant cold packs use endothermic reaction that release or absorb thermal energy.

Answer:

mass= 206.4 g

Explanation:

Density= mass/volume

0.86=x/240

x=240×0.86

=206.4g

The density of butter is 0.86 g/cm³. 206.4g is the mass of 240 cm³ of butter. The phrase "specific volume" is occasionally used in thermodynamics to refer to a substance's reciprocal of its density.

Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre. Density can also be expressed as kilograms per cubic metre (in metre-kilogram-second or SI units). For example, the density of air is 1.2 kilograms per cubic metre.

Density= mass/volume

Explanation:

Answer:

The answer is D.

Explanation:

Volume (V) = l x w x h

V = 4 x 5 x 1.2

V = 20 x 1.2

V = 24

Density = Mass/Volume  or D = M/V  

D = 85,000/24

Mechanical

Explanation:

Since, this mechanical energy gets converted into thermal energy due to which hairs get dry. Thus, we can conclude that the energy transformation that occurs when a hair dryer is plugged in and turned on is that electrical energy transforms into mechanical and thermal energy.

Answer:

The acceleration of the car is 0.0273.

Explanation:

We can find this by using the acceleration formula which is:

a = ( vf - vi ) / Δt

a is acceleration.

vi is the initial velocity.

vf is the final velocity.

When we substitute into the equation we get. . .

a = ( 6.4 - 4.9 ) / 3

and when we solve this equation we get 0.02734
