Answer:
The neutrons have no charge
Explanation:
im not sure about the second part. good luck
The conversion factor between yards to inches is 1 yard is equal to 36 inches. In converting 16.7 inches to yards, one must simply multiply it with the conversion factor.
16.7 inches *(1 yard/36 inches) = <span>
<span>0.463888889 yards
The answer is 0.46 yards.</span></span>
Explanation:
To calculate that you need to know the value of the Kps (constant of solubility) at 30°C of KBr in water.
<u>When the product of the concentrations of both ions (Br- and K+) equals the Kps, the solution is saturated. </u>
Given the disociation of the salt in water:
The concentration of both ions are equal (1:1 ratio) and the same as the concentration of KBr added.
The Kps:
[KBr] are <u>moles of the salt per litre of water</u>
Assuming a density of water of 1 g/cm3, 100 g are 0.1 litre
To calculate the mass:
where M is the molecular weight of the salt.
Answer:
0.299 moles of PCl5
Explanation:
First form an equation based of given information: P4 + Cl2= 4PCl5
Next balance it: P4 + 10Cl2 = 4PCl5
Take your given value (53.0g of Cl2) and divide it by its molar mass to get moles of Cl2: 53.0g/70.906g = 0.747 moles Cl2
Then, multiply by the molar ratio (10Cl2 to 4PCl5): (0.747 x 4 mol PCl5)/10 mol Cl2 = 0.299 moles PCl5
Answer:
i dont know if this is right im sorry if isnt but here you go
Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
