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.
That act will help the sustainability of out environment because : C. It will slow down the degradation of the ozone layer
The usage of CFC will crate chlorine atoms that catalyze ozone degradation. By prohibiting this product, Government will slow down Ozone's degradation
hope this helps
Answer:the largest taxon is kingdom and it is divided into phylum class order genus species
Explanation:
Concentration gradient, size of the particle, and temperature are all factors
Olds and Milner showed that electrical stimulation of particular brain regions could have a reinforcing effect.
<h3>Electrical brain stimulation</h3>
it is commonly known as focal brain stimulation (FBS), is a type of electrotherapy used in clinical neurobiology and research to activate a neuron or neural network in the brain by either directly or indirectly stimulating its cell membrane with an electric current.
<h3>What is the purpose of brain electrical stimulation?</h3>
- Electrical stimulation can be used to alter how the brain functions because electrical charges are what cause brain activity.
- Brain stimulation has been used to treat stress and mood disorders, and it can even make it easier for people to remember things, solve puzzles, and pay attention.
