Answer:

Option d. 2615.0g

Explanation:

Let M1, M2, and M3 represent the masses of the three different samples

M1 = 0.1568934 kg = 156.8934g

M2 = 1.215mg = 1.215x10^-3 = 0.001215g

M3 = 2458.1g

Total Mass = M1 + M2 + M3

Total Mass = 156.8934 + 0.001215 + 2458.1

Total Mass = 2614.994651g

Total Mass = 2615.0g

Describe the oxygen/carbon dioxide cycle using plants and animals.
Vikentia [17]

Answer:

The process of photosynthesis in plants releases oxygen into the atmosphere. Respiration by plants and animals, as they use the energy stored in food, and the process of decomposition of dead organisms, releases carbon dioxide into the atmosphere. All three work together to maintain the carbon dioxide-oxygen cycle.

Some water released 7800 J of energy when cooled from 78°C to 33°C. What was the mass of the water?
Karo-lina-s [1.5K]

Answer:

-41. 47

Explanation:

m = q / Cp x T

m = Mass

q = Energy (or joules)

Cp = Heat Capacity

T = Change in Temperature

Water's heat capacity is always 4.18.

This is the formula you'll need for change in temperature:

Final - Initial

So, 33 - 78 = -45

m = 7800 / 4.18 x -45

= -41.47

Two types of heterogeneous mixtures are suspensions and colloids.<br>true or false<br><br>​
scoray [572]
<h2>Answer:True</h2>

Explanation:

Heterogeneous mixture is a mixture with non-uniform composition.

The properties of the mixture like concentration may change for different parts of the mixture.

Colloids contain solute particles of size 2nm-500nm.The presence of these particles makes the mixture heterogeneous.

Suspensions contain solute particles of size 500nm-1000nm.These particles settle to the bottom of the mixture which makes the composition of the bottom different from the top.

So,colloids and suspensions are two types of heterogeneous mixtures.
