1. How many joules must be added to 10.0 g of water to raise its temperature from 10°C to<br> 15°C?
weqwewe [10]

Answer:

209.3 Joules require to raise the temperature from 10 °C to 15 °C.

Explanation:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m × c × ΔT

Given data:

mass of water = 10 g

initial temperature T1= 10 °C

final temperature T2=  15 °C

temperature change =ΔT= T2-T1 = 15°C - 10°C = 5 °C

Energy or joules added to increase the temperature Q = ?

Solution:

We know that specific heat of water is 4.186 J/g .°C

Q = m × c × ΔT

Q = 10 g × 4.186 J/g .°C × 5 °C

Q = 209.3 J

Calculate the molarity of 29.9 g of MgS in 911 mL of solution??
LUCKY_DIMON [66]

0.58 is the molarity of 29.9 g of MgS in 911 mL of solution.

Define the molarity of a solution.

Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.

Given data:

Volume of solution = 911 mL=0.911L

Given the mass of  MgS = 29.9 g

Molar mass of MgS = 56.38 g/mol

Moles of MgS = 0.5303299042

Molality = \frac{Moles \;solute}{Volume \;of \;solution \;in \;litre}

Molality = \frac{0.5303299042}{0.911L}

Molality = 0.5821403998=0.58

Hence,  0.58 is the molarity of 29.9 g of MgS in 911 mL of solution.

Lana71 [14]

Answer:

Diamond - E

Sugar- C

Milk - M

Iron- E

Air- M

Sulfuric Acid- C

Gasoline - M

Electricity- X

Krypton- E

Bismuth - E

Uranium - E

Kool-Aid -M

Water - C

Alcohol - C

Pail of Garbage - M

Ammonia - C

Salt - C

Energy - X

Gold - E

Wood - M

Bronze - M

Ink - M

Pizza - M

Dry Ice - C

Baking Soda - C

Explanation:

An element is the smallest part of a substance that is capable of independent existence. An element cannot be broken down into any other substance. Krypton, Bismuth etc are all elements.

A compound is a combination of two or more elements which are chemically combined together e.g NH3, CO2 etc.

A mixture is any combination of substances that are not chemically combined together. E.g Pizza, milk etc
