Answer:
Explanation:
Hello,
At first, the moles of magnesium sulfate must be computed by knowing that its molecular mass has a value of 120.366 g/mol:
Now, by knowing that the volume must be in L, it turns out into 0.10000 L, thus:
Best regards.
Answer:
Element Y, or the third option
Explanation:
Alkanes are insoluble in water, but soluble in ether. Their boiling points are pretty low, barely reaching 200 degrees, so element Y is an alkane.

The various levels of the organization of life are as follows:
Cells: a cell is the basic unit of ife
Tissues; A tissue is a group of cells with a common origin. performing similar functions.
Organ: an organ is a group of tissues with varied or similar function that work together to perform a specific function.
System: a system is a group of different organs that work together in the body to perform a specific function.
Since, the leaf is an organ in the plant that performs the function of photosynthesis, the group of dermal cells found on the leaf are in the tissue level of organization, they perform the function of protection for the leaf.

Answer:</h3>
1031.4 Calories.
<h3>
Explanation:</h3>
We are given;
Mass of the copper metal = 50.0 g
Initial temperature = 21.0 °C
Final temperature, = 75°C
Change in temperature = 54°C
Specific heat capacity of copper = 0.382 Cal/g°C
We are required to calculate the amount of heat in calories required to raise the temperature of the copper metal;
Quantity of heat is given by the formula,
Q = Mass × specific heat capacity × change in temperature
= 50.0 g × 0.382 Cal/g°C × 54 °C
= 1031.4 Calories
Thus, the amount of heat energy required is 1031.4 Calories.
