Answer:
There are 10 moles of copper(II)sulfate.
Explanation:
We know that molarity is a concentration measure that expresses the moles of solute per liter of solution: in this case, being 1.30 molar, there are 1.30 moles of solute in 1 liter of solution. We solve with the following simple rule of three:
1 L solution-----2 moles of copper(II)sulfate
5 L solution----x= (5 L solution x 2 moles of copper(II)sulfate)/1 L solution
<em>x= 10 moles of copper(II)sulfate</em>
False, it’s not mechanical energy it’s thermal energy.
Answer:
Helps eliminate waste products such as urea, uric acid ammonia, and other products via urine.
It helps maintain the osmotic level of blood and plasma.
It helps maintain the electrolyte balance in the body.
And it also helps in the metabolism of those drugs that do not get metabolized in the liver.
Explanation:
<em>"The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the body of used up and broken down components in a liquid and gaseous state"</em>
Answer:
The mass of silver is 49 g (0.049 kg).
Explanation:
Initial temperature = 
C
Final temperature = 
C
Quantity of heat required = 117.5 J
Specific heat capacity of silver = 0.240 J/g
mass of the silver can be determined by;
Q = mcΔθ
Where: Q is the quantity of heat required, m is the mass of substance, c is the specific heat capacity of the substance and Δθ is the change in temperature.
So that,
117.5 = m x 0.240 x (40 - 30)
117.5 = m x 0.24 x 10
= 2.4m
m = 
= 48.9583
m ≅
m = 49 g
The mass of silver is 49 g (0.049 kg).
8m of hydrogen will react with 1 mol of sulfur.
