Answer:
0.062 moles of hydrogen gas
Explanation:
We must first out down the reaction equation before we can attempt to solve the problem.
Mg(s) + 2HCl(aq) ----> MgCl2(aq) + H2(g)
Next we obtain the number of moles in 1.5 g of magnesium metal from;
Molar mass of magnesium = 24.3 gmol-1
Number of moles of magnesium= mass/molar mass = 1.5g/24.3gmol-1 = 0.062 moles
From the reaction equation;
1 mole of magnesium metal yields 1 mole of hydrogen gas
0.062 moles of magnesium metal will yield 0.062 moles of hydrogen gas
Therefore, reaction of 1.5g of magnesium metal with excess hydrochloric acid will yield 0.062 moles of hydrogen gas.
Answer:
They all came from the big bang.
Explanation:
A few things:
<span>1. it secretes insulin, which the body uses to utilize glucose (in the kind of diabetes most people have, their tissues have become resistant to insulin requiring more and more of it to be produced by the pancreas) </span>
<span>
2. it produces things called pancreatic enzymes which help us digest foods (especially fatty ones) </span>
<span>
3. the other things it secretes are somatostatin which regulates growth hormone, and glucagon which is related to insulin in that it also helps regulate the body's sugar (kind of an anti-insulin) </span>
The egg cell must first be enucleated through the process of removing the nucleus from the surrogate mother’s egg. An adult cell nucleus from the desired mother is then inserted into the enucleated egg. This combination of adult cell nucleus inside the enucleated egg must now be stimulated with an electric shock. This will cause the start of cell division by mitosis to eventually form an embryo in the uterus of the surrogate mother whom the initial enucleated egg belonged to.
