What effect does temperature have on the characteristics of magma?
The temperature of the magma will affect its viscosity depending on its chemistry. Some minerals crystallize at higher temperatures than others, meaning that portions of the magma may have already solidified. At lower temperatures, the majority of the constituent minerals will have crystallized and solidified, leaving the magma highly viscous.

Carbon exists in nature as three isotopes. Given the atomic masses and relative abundance of the isotopes, what is the average a
Ivan

The most abundant carbon isotope is carbon-12.

The relative atomic mass of carbon is 12.011, which is extremely close to 12.0. This means that the masses C-13, and C-14 are practically negligible when contributing to the relative atomic mass of carbon.

the C-12 isotope makes up 98.9% of carbon atoms, C-13 makes up 1.1% of carbon atoms, and C-14 makes up just a trace of carbon atoms as they are found in nature.

Your boss asks you to design a room that can be as soundproof as possible and provides you with three samples of material. The o
Svetach [21]
My Choice will be the sample C with a coefficient of absorption 62 % and the reason is that the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest. Because this sample has the highest percentage of the coefficient of absorption than the other samples, As the sound Absorption coefficient is a part of the sound energy that absorbed by a material.And Its value varies with the angles of incident and frequency. So sample C is the best to be used as a soundproof room.

When excess dilute hydrochloric acid was added to sodium sulphite 960 of sulphuric (iv) oxide was produced. calculate the mass o
irakobra [83]

The mass of sodium sulfite that was used will be 1,890 grams.

<h3>Stoichiometric problems</h3>

First, the equation of the reaction:

NaSO_3 + 2HCl --- > NaCl_2 + H_2O + SO_2

The mole ratio of SO2 produced and sodium sulfite that reacted is 1:1.

Mole of 960 grams SO2 = 960/64 = 15 moles

Equivalent mole of sodium sulfite that reacted = 15 moles

Mass of 15 moles sodium sulfite = 15 x 126 = 1,890 grams

If you find the mass of a sample to be 42.1 g and the actual mass is 42.0 g. your percent error would be what?
melomori [17]

Answer:

0.24%

Explanation:

To find the percent error, first subtract the actual value by the expected value.  You can ignore the sign of the difference.

42.0 - 42.1 = -0.1 = 0.1

Divide the difference by the expected value and multiply by 100%.

0.1/42.1 = 0.0024 × 100% = 0.24%

The percent error is 0.24%.

A plate moves 200 m in 10,000 years. What is its rate in cm/year?
Varvara68 [4.7K]

Answer:

The answer is

<h2>2 cm/year</h2>

Explanation:

To find the rate in cm/year we must first convert 200 m into cm

1 m = 100 cm

if 1 m = 100 cm

Then 200 m = 200 × 100 = 20 ,000 cm

So the rate is

<h2>\frac{20000}{10000}</h2>

<u>Reduce the fraction with 10,000</u>

We have the final answer as

<h3>2 cm/year</h3>

Hope this helps you
