Your system could not cool as effectively as it should due to refrigerant leakage. Your home cannot reach the target temperature due to your air conditioning system. However, it may also result in higher monthly energy costs.

<h3>What is the temperature called?</h3>

Temperature is a unit used to represent hotness or coolness on any of a number of scales, including Celsius and Fahrenheit. According to temperature, heat energy will naturally move from a hotter (body with a high temp) to a colder (body with such a lower temperature) (one at a lower temperature)

<h3>What are the 4 types of temperature?</h3>

The most widely used method of measuring temperature in the United States and several Caribbean regions is the Fahrenheit scale.
Celsius Scale.
Kelvin Scale.
Rankine Scale

Epsom salt is commonly purchased in the pharmacy for a variety of uses, anti-inflammatory, laxative, and cosmetic. epsom salt is

Dominik [7]

Epsom salt is MgSO4.
We assume x water of hydration in the crystalline form.

Molecular mass of MgSO4 = 24+32+4*16=120
Molecular mass of MgSO4.xH2O = 120+18x

By proportion,
2.000/0.977 = (120+18x)/120
Cross multiply
0.977(120+18x) = 120*2.000
from which we solve for x
17.586x+117.24 = 240
x=122.78/17.586
=6.980

Answer: there are 7 water of hydration in Epsom salt, according to the experiment.

Note: more accurate (proper) results may be obtained by using exact values (3-4 significant figures) in the molecular masses. However, since water of hydration is the nearest integer, using approximate values (to at least two significant figures) suffice.

How many copper atoms are in 150 g of copper metal

GaryK [48]

1. From grams -> mole:

=grams given x 1 mol/molar mass

So 150 g Cu x 1 mol Cu/63.546 g Cu = 2.4 mol Cu

2. From mole -> atoms

=number of mol x 6.022x10^22 atoms/1 mol

So 2.4 mol Cu x 6.022x10^22 atoms Cu/1 mol Cu = 1.4 x 10^24 atoms Cu

A compound was found to have 85.7% carbon and 14.3% hydrogen. Its molecular mass is 84. What is its empirical formula? What is i

Ludmilka [50]

Answer:

The molecular formula is C₆H₁₂

The empirical formula is CH₂

Explanation:

Percent by mass, means that in 100 g of compound we have:

85.7 g of C

14.3 g of H

Let's make a rule of three with the molar mass to determine the amounts of the elements:

In 100 g of compound we have 85.7 g of C

In 84 g of compound we would have (84 . 85.7) / 100 = 72 g of C

In 100 g of compound we have 14.3 g of H

Then, in 84 g of compound we would have (84 . 14.3) / 100 = 12 g of H

Now let's determine the moles of each element

72 g of C / 12 g/mol = 6 mol of C

12 g of H / 1 g/mol = 12 mol of H

Then, the molecular formula is C₆H₁₂

The empirical formula is CH₂
