(a) the forward reaction is exothermic. (b) the forward reaction is endothermic. (c) the ice bath lowered the activation energy. (d) the ice bath raised the activation energy.
The mixture as per the question is endothermic reaction when the contents of the tube containing the equilibrium mixture turned a lighter color whenever the tube was placed into an ice bath.
Activation energy can be defined as the minimum energy required by particles at the reactant side for a chemical reaction to occur. According to the reaction conditions, specifically for reversible reactions, reactants can in turn become products and vice versa.
Exothermic reaction can be defined as the process where the heat energy is liberated in the conversion of the reactants to products for the forward reaction. We know that the heat is created in this process a small part of the energy may be initially provided to activate the reactant particles but once the reaction is in ongoing state it produces good amount of heat energy to keep the process in flow.
The reverse reaction, we know that is the endothermic in nature. The heat energy is absorbed in the conversion of the products ( now reactants in the reverse reaction ) to reactants ( now products in the reverse reaction ), as a result of this more amount of energy has to be initially and continuously supplied for them to overcome the activation energy barrier for the reverse reaction to occur and be sustained.

If the rate of consumption of magnesium is 5.0 × 10^-9 mol/s. find the rate of consumption of HCl in moles/s
In order to find the rate of consumption of HCl in moles/s, you would need to know the balanced equation for the chemical reaction involving magnesium and HCl.
One common reaction is the reaction between magnesium and hydrochloric acid:
Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
If the rate of consumption of magnesium is 5.0 × 10^-9 mol/s, this means that 5.0 × 10^-9 moles of magnesium are being consumed per second. In this reaction, one mole of magnesium reacts with 2 moles of HCl, so for every mole of magnesium consumed, 2 moles of HCl are also consumed.
Therefore, the rate of consumption of HCl in moles/s can be calculated by multiplying the rate of consumption of magnesium by 2:
rate of consumption of HCl = (rate of consumption of Mg) * 2
rate of consumption of HCl = (5.0 x 10^-9 mol/s) * 2 = 1.0 x 10^-8 mol/s
So the rate of consumption of HCl in moles/s is 1.0 x 10^-8 moles/s.

How many grams of Ag will be produced from 5.00 g of Cu and 1.00 g of AgNO3?
Answer:
0.648 g of Ag ( silver) is produced
Explanation:
First calculating the moles of the reactants given;
Cu = 5/64 = 0.078 moles
Mr ( molecular mass) of AgNO3 = 108 + 14 + (16 x 3)
= 170 g
Now the moles of AgNO3 ;
1/170 = 0.006 moles
setting up mole ratio to calculate the limiting reactant:
moles of Cu : moles of Ag
1 : 2
0.078 : X
X = 0.078 x 2
= 0.156 moles of Ag
moles of AgNO3 : moles of Ag
2 : 2
0.006 : X
X = (0.006 x 2)/2
= 0.006 moles of Ag
As silver nitrate ( AgNO3) gives the least number of moles of Ag therefore it is the limiting reactant and would control the amount of product formed.
Now the mass of Ag formed:
atomic mass x moles
= 108 x 0.006
= 0.648 g of Ag ( silver) is produced

A compound's empirical formula is a formula that displays the ratio of the elements contained in the compound but not the precise number of atoms present in the molecule.
The molar mass of phosphorus (P) is 31 g/mol and selenium (Se) is 79 g/mol. Then, computing the moles of phosphorus, we get,
[tex]\begin{aligned}\text{moles of P}&=\mathrm{0.04\;g}\times\mathrm{\frac{1\;mole}{31\;g}}\\&=\mathrm{1.29\times10^{-3}\;moles}\end{aligned}[/tex]
The total mass is 77.6 mg. Then, the mass of selenium is (77.6-40)mg=37.6 mg=0.0376 g. Computing the moles of selenium, we get,
[tex]\begin{aligned}\text{moles of Se}&=\mathrm{0.0376\;g}\times\mathrm{\frac{1\;mole}{79\;g}}\\&=\mathrm{0.476\times10^{-3}\;moles}\end{aligned}[/tex]

Which of the following occurs first in synaptic transmission once the action potential reaches the end bulbs
Once an action potential reaches the end bulbs of a neuron, the first event in synaptic transmission is the release of neurotransmitters from the presynaptic neuron.
When an action potential reaches the end bulbs, it causes the opening of voltage-gated calcium channels in the presynaptic membrane. This influx of calcium ions into the presynaptic neuron triggers the release of neurotransmitters stored in vesicles at the synapse.
The neurotransmitters then diffuse across the synaptic cleft, the small space between the presynaptic and postsynaptic neurons, and bind to receptors on the postsynaptic membrane. This binding causes a change in the electrical or chemical properties of the postsynaptic neuron, leading to the initiation or inhibition of an action potential in the postsynaptic neuron.
It's worth noting that, this process is called synaptic transmission, it's the process by which an action potential in one neuron causes an electrical or chemical signal in another neuron, muscle cell or gland cell.

Assigning people on the basis of chance ensures that both known and unknown invalidating factors are cancelled out, and that this occurs automatically rather than being dependent on individual judgment and trustworthiness. In behavioral and social (as well clinical) research, the ideal scientific experiment is a so-called randomized controlled trial, briefly an RCT.
Members of control groups are not supposed to develop group cohesion because that would entail a contaminating factor in the experiment. Researchers are interested in the average response of individual members rather than in their behavior as a group (see Clinical Trials and Intervention Studies).
