Answer:
The hormone glucagon secreted by the pancreatic cells cause the release of glucose from the body's storage.
Explanation:
The pancreas is an organ found inside the abdomen. This organ produces hormones such as:
- Insulin
- Glucagon
- Somatostatin
- Vasoactive intestinal peptide
Insulin and glucagon are considered primary hormones secreted by the pancreas.
Upon skipping a meal, leading to a drop in blood sugar levels, glucagon is secreted by the pancreas. This hormone then acts on the liver to stimulate the conversion of stored up glycogen present in the liver into glucose. This produced glucose is then released into the blood stream, availing the boy glucose for energy.
Answer:
HCl is the limiting reactant. It will completely be consumed (1.37 moles)
Option D is correct
Explanation:
Step 1: Data given
Mass of Zinc (Zn) = 50.0 grams
Mass of Hydrogen chloride (HCl) = 50.0 grams
atomic mass Zn = 65.38 g/mol
Molar mass HCl = 36.46 g/mol
Step 2: The balanced equation
Zn + 2HCl → ZnCl2 + H2
Step 3: Calculate moles
Moles = mass / molar mass
Moles Zn = 50.0 grams / 65.38 g/mol
Moles Zn = 0.764 moles
Moles HCl = 50.0 grams / 36.46 g/mol
Moles HCl = 1.37 moles
Step 4: Calculate limiting reactant
For 1 mol Zn we need 2 moles HCl to produce 1 mol ZnCl2 and 1 mol H2
HCl is the limiting reactant. It will completely be consumed (1.37 moles)
Zn is in excess. There will react 1.37/2 = 0.685 moles
There will remain 0.764 -0.685 = 0.079 moles
Answer:
The reaction will occur, in the forward direction, and NiO will be reduced to Ni
Explanation:
Step 1: Data given
Kp = 6.0 * 10²
Pressure of CO = 150 torr
Total pressure never exceeds 760 torr
Step 2: The balanced equation:
NiO(s) + CO(g) ⇆ Ni(s) + CO2(g)
Step 3: Calculate P(CO) and P(CO2)
For this equilibrium, the expression for Kp is:
Kp = P(CO2)/P(CO) = 6.0*10^2
(NiO and Ni are solids so do not change anything to the Kp
⇒ with P(CO) = 150 torr
⇒ P(CO) = 760 - 150 = 610 torr
Step 4: Calculate the reaction quotient
Q = 610/150 = 4.1
Q<<< Kp
There are more reactants than products. As a result, some of the reactants will become products, causing the reaction to shift to the right.
This means the reaction will proceed in the forward direction, and NiO will be reduced to Ni.
