Answer:
an electron is part of the 3 things that are in an atom, it has a negative charge
Pretty sure it’s Mixture if I’m not wrong
Answer:
K = 3.37
Explanation:
2 NH₃(g) → N₂(g) + 3H₂(g)
Initially we have 4 mol of ammonia, and in equilibrium we have 2 moles, so we have to think, that 2 moles have been reacted (4-2).
2 NH₃(g) → N₂(g) + 3H₂(g)
Initally 4moles - -
React 2moles 2m + 3m
Eq 2 moles 2m 3m
We had produced 2 moles of nitrogen and 3 mol of H₂ (ratio is 2:3)
The expression for K is: ( [H₂]³ . [N₂] ) / [NH₃]²
We have to divide the concentration /2L, cause we need MOLARITY to calculate K (mol/L)
K = ( (2m/2L) . (3m/2L)³ ) / (2m/2L)²
K = 27/8 / 1 → 3.37
Answer: An increase in the ratio of insulin to glucagon will increase the activity of --
- Acetyl-CoA carboxylase(+)
-Phosphofructokinase PFK2(+)
-Glycogen synthase(+)
- Hormone sensitive lipase (-). The hormone sensitive lipase activity is not increased with increased insulin activity.
Explanation: increased insulin - glucagon ratio is usually high in fed state.Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.
Answer is: no reaction occurs, because all salts are soluble in water.
Balanced chemical reaction:
Zn(NO₃)₂(aq) + MgSO₄(aq)→ Mg(NO₃)₂(aq) + ZnSO₄(aq).
Ionic reaction:
Zn²⁺(aq) + 2NO₃⁻(aq) + Mg²⁺(aq) + SO₄²⁻(aq) → Mg²⁺(aq) + 2NO₃⁻(aq) + Zn²⁺ + SO₄²⁻(aq).
This chemical reaction is double displacement reaction - cations and anions of the two reactants switch places and form two new compounds.
