Metamorphic rock is formed from the weathering, erosion and cementing of sediments.

True
False

Answers

Answer 1

Answer:

False

Explanation:

Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

This question is reffering to sedimentary rocks, so it's false.

Answer 2

Answer:

Weathering (breaking down rock) and erosion (transporting rock material) at or near the earth's surface breaks down rocks into small and smaller pieces. When the molten rock cools it forms an igneous rock. Metamorphic rocks can form from either sedimentary or igneous rocks.

Explanation:

True

Scientists often look at how much isotopes of ______
have decayed to help estimate the age
of a fossil or once-living material.

Answers

Answer:

If im correct it’s radioisotope

Explanation:

Scientists often look at how much of isotopes of : Carbon-14  have decayed

To determine the age of fossils archeologist make use of the carbon-14 dating ( i.e. making use of naturally occurring radioisotope ¹⁴C ) which is used to determine the age of fossils or material that were once in living on earth.

Carbon has about three (3) isotopes ( Carbon-12, Carbon-13 and Carbon-14 ) .but Carbon-14 isotope is most useful in determining the age of fossils and once-living things

Hence we can conclude that scientists often look at how much of isotopes of Carbon-14 have decayed to help estimate the age of fossils.

How many grams are in 25.0 moles of carbon tetrachloride (CCI)?

Answers

Answer:

3.84 kg

Explanation:

CCl4 molar mass: 153.82 g/mol

n = mass / molar mass

25 moles = mass / 153.82 g/mol

mass = 25 x 153.82

mass = 3845 g or 3,84 kg

The boiling point of ethanol is 78.3 degrees Celsius. The boiling point of

ethanol on the Kelvin scale is approximately... *

Answers

Answer:

K = 351.3

Explanation:

The relationship between the Celsius scale and kelvin scale is;

K = 273 + C

Since the Celsius temperature = 78.3

The kelvin temperature is given as;

K = 273  + 78.3

K = 351.3

You need to make an aqueous solution of 0.150 M sodium fluoride for an experiment in lab, using a 500 mL volumetric flask. How much solid sodium fluoride should you add?

Answers

Answer:

Explanation:

Solution required is .15 M 500 mL sodium fluoride .

molecular weight of sodium fluoride = 42

one mole of sodium fluoride = 42 grams

No of moles contained in the solution of .15M , 500 mL solution

= .15 x 0.5 moles = .075 moles

1 mole = 42 g

.075 moles = .075 x 42 = 3.15 grams .

So mass of sodium fluoride required = 3.15 g .

When a compound such as X2Z4 is created, what would be the
correct simplified chemical formula?

Answers

Answer:

XZ2

Explanation:

There are different ways in which compounds can be represented. Broadly, we have three different types of formula;

- Structural formular: This shows how th atoms in te compound are connected to each other.

- Molecular formular: This shows the actual number of atoms of element present in the compound

- Empirical Formular: This is the simplest formular of a compound. It basically shows the number of atoms in simple ration to each other.

This question requires us to input the empirical formular;

X2Z4

The ratio of the elements is; 2 : 4 which can be simplified into 1 : 2

This means the empirical formular is XZ2

Answers

Answer:

36°C

Explanation:

Given parameters:

Mass of aluminum = 725g

Quantity of heat  = 2.35 x 10⁴J

Unknown:

Temperature change  = ?

Solution:

To solve this problem, we simply use the expression below:

  The quantity of energy is given as:

          Q  = m C Δt

Q is the quantity of energy

m is the mass

C is the specific heat capacity of aluminum  = 0.9J/g°C

Δt is the change in temperature

  The unknown is Δt;

             Δt  = [tex]\frac{Q}{mc}[/tex]    = [tex]\frac{2.35 x 10^{4} }{725 x 0.9}[/tex]    = 36°C

Predicting the future based solely on the position of the planets is an example of pseudoscience.

Pseudoscience is a body of knowledge that is not based on the scientific method but on some unverifiable/unprovable claims.

Predictions about the future can only be valid if it is based on the scientific method, not just about the position of the planet. The scientific method involves observation, hypothesis formulation, testing of the hypothesis through repeatable experiments, and arriving at conclusion.

Any other statement or belief that is not based on these procedures is said to be pseudoscientific.

During the naval battles of the South Pacific in World War II, the U.S. Navy produced smoke screens by spraying titanium tetrachloride into the moist air where it reacted according to the equation:
TiCl4 + H2O TiO2 + HCl

a. How many moles of H2O are needed to react with 6.50 moles of TiCl4? (13.0)

b. How many moles of HCl are formed when 8.44 moles of TiCl4 react? (33.8)

Answers

Explanation:

The reaction given is;

TiCl4 + H2O --> TiO2 + HCl

The reaction is not balanced, upon balancing it is given as;

TiCl4 + 2H2O → TiO2 + 4HCl  

a. How many moles of H2O are needed to react with 6.50 moles of TiCl4?

From the reaction;

1 mol of TiCl4 requires 2 mol of H2O

6.50 mol of TiCl4 would require x mol of H2O

1 = 2

6.5 = x

x = 6.5 * 2 / 1 = 13.0 mol

b. How many moles of HCl are formed when 8.44 moles of TiCl4 react?

From the equation of the reaction;

1 mol of TiCl4 reacts to form 4 mol of HCl

8.44 mol of TiCl4 reacts to form x mol of HCl

1 = 4

8.44 = x

x = 8.44 * 4 / 1 = 33.76 mol

Answers

Answer:

Zn. + 2 HCl ----------> ZnCl2. + H2

Explanation:

Mass of Zn in mole = 3.27/ 65.38= 0.050010.... mol

Mass of HCl in mole = 3.3/ 73= 0.044....mol

Hence, limiting reagent is HCl

Molar mass of ZnCl2= 136.38g

Let mass of ZnCl2 be x
