Answer:

Heat transferred in the process is 19019J

Explanation:

Using the equation:

Q = S×m×ΔT

We can solve the energy transferred in the process, Q, where:

S is specific heat = 4.18J /(g°C)

m is mass = 350g

ΔT is change in temperature (21°C - 8°C = 13°C)

Q = 4.18J/(g°C)×350g×13°C

Q = 19019J

<h3>Heat transferred in the process is 19019J</h3>

A steel cylinder has a pressure of 550 torr at 177 degrees Celsius. What will be the pressure if the temperature is decreased by
Schach [20]

Answer:

P_2=507.7torr

Explanation:

Hello there!

In this case, when we have a gas that is undergoing a change in both pressure and temperature, we utilize the Gay-Lussac's equation as shown below:

\frac{T_2}{P_2}=\frac{T_1}{P_1}

Thus, since we are given the initial pressure and temperature and the final temperature, we can compute the final pressure as shown below:

P_2=\frac{P_1}{T_1}*T_2

So we plug in, by making sure the temperatures are in kelvins, to obtain:

P_2=\frac{550torr}{(117+273)K}*(87+273)K\\\\P_2=507.7torr

Best regards!

Composition of matter (compound, mixture, element)​
slava [35]

Explanation:

Matter can be classified into two broad categories: pure substances and mixtures. ... A material composed of two or more substances is a mixture. Elements and compounds are both examples of pure substances. A substance that cannot be broken down into chemically simpler components is an elementOne useful way of organizing our understanding of matter is to think of a hierarchy that extends down from the most general and complex to the simplest and most fundamental (Figure 3.4.1 ). Matter can be classified into two broad categories: pure substances and mixtures. A pure substance is a form of matter that has a constant composition (meaning that it is the same everywhere) and properties that are constant throughout the sample (meaning that there is only one set of properties such as melting point, color, boiling point, etc. throughout the matter). A material composed of two or more substances is a mixture. Elements and compounds are both examples of pure substances. A substance that cannot be broken down into chemically simpler components is an element. Aluminum, which is used in soda cans, is an element. A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound. For example, water is a compound composed of the elements hydrogen and oxygen. Today, there are about 118 elements in the known universe. In contrast, scientists have identified tens of millions of different compounds to date.

How many grams of magnesium metal will react completely with 4.8 liters of 5.0 M HCl? Show all of the work needed to solve this
vovikov84 [41]
V=4.8 L
c=5.0 mol/L
M(Mg)=24.3 g/mol

1) n(HCl)=cv

2) m(Mg)=M(Mg)n(HCl)/2

3) m(Mg)=M(Mg)cv/2
    m(Mg)=24.3*5*4.8/2=291.6 g

How are the pressure and temperature of a gas related
expeople1 [14]

Answer:

The pressure of a given amount of gas is directly proportional to its absolute temperature, provided that the volume does not change (Amontons's law). ... The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law).
