circle the correct terms for the reaction going from left to right. reactant a gains/loses and electron to become product B

Effectus [21]

The question requires one to indicate the correct terms for the reactant from left to right.

<h3>What is a reactant?</h3>

A reactant is a material that enters and changes during a chemical reaction.

1. Reactant A (Gains/Loses) and electron to become product B

To produce B, reactant A loses one electron. The loss of one electron from an atom causes the atom to be oxidized.

Reactant A gives an electron to NAD+ and is transformed to B+ in the given reaction there is an increase in the positive charge. As a result, reactant A is oxidized to produce B+.

2. NAD+ becomes reduced in the process of the reaction.

NAD+ receives the electron given to it by reactant A and is reduced to NADH. As a result, the positive charge of NAD+ decreases.

3. NADH is more reduced than NAD+

NAD+ receives an electron and becomes NADH. As a result, NADH is decreased more than NAD+

4. NAD+ is in the more oxidized state compared to NADH

NAD+ has a surplus of positive charge as opposed to NADH. NAD+ must receive one electron in order to produce NADH. As a result, as opposed to NADH, NAD+ is more oxidized.

5. Reactant A is the electron donor in this reaction.

Reactant A loses one electron, resulting in positively charged B+. This electron is taken up by NAD+, which reduces to NADH. As a result, the electron donor is reactant A.

6. Reactant A is the reducing agent in this reaction.

A reducing agent is a molecule that can transfer electrons.

Such a molecule has the potential to decrease another molecule while also becoming oxidized. Reactant A is the reducing agent in the given reaction, donating an electron to NAD+.

Following the electron transfer, reactant A is oxidized to product B+, and NAD+ is reduced to NADH.

37 cos(x2) dx 0 Do the following. (a) Find the approximations T8 and M8 for the given integral. (Round your answer to six decima

dusya [7]

The approximations T8 and M8 for the given integral are:

T8 = 33.386321; and
M8 = 33.50794

<h3>What is an integral?</h3>

An Integral is a variable of which a given function is the derivative, i.e. it gives that function when differentiated and may express the area under the curve of the function's graph.

<h3>What is the explanation to above answer?</h3>

Given:

F(x) = 37 cox (x²)

Internal = [0,1] n = 8 in Δ x = 1/8

The sub intervals are:

[0, 1/8], [1/8, 2/8], [2/8, 3/8], [ 3/8, 4/8], [ 4/8, 5/8], [ 5/8, 6/8], [6/8, 7/8], [ 7/8, 1]

The mid points are given as:

1/16, 3/16, 5/16, 7/16, 9/16, 11/16, 13/16, 15/16

and X₀ = 0, X₁ = 1/8, X₂ = 2/8

Using the Trapezium Rule which states that:

$\int\limits^1_0 cos(x)^{2} } \, dx$ = Δx/2 $[f(xo) + 2f(x1) 2f(x2) + ....+ 2f(x7) + f(x8)]$

= 1/1Q[f(0) + 2f (1/8) + 2f(2/8) + ....+ 2f(7/8) + f(1)]

= 0.902333

Now

T8 = $\int\limits^1_0 {37Cos(x)^{2} } \, dx$

= $37\int\limits^1_0 {(0.902333)} } \, dx$

= 37 (0.902333)

T8 = 33.386321

It is to be noted that the midpoints rule is given as;

$\int\limits^1_0 {Cos(x)^{2} } \, dx$ = Δx [f(1/16) + (3/16) + .... + f(15/16)]

= 1/8[f(1/16) + f (3/16) + f(5/16) + f(7/16) + f(9/16) + f(11/16) + f(13/16) + f(15/16)]

= 0.905620

From the above,

M8 = $\int\limits^1_0 {37 Cos(x)^{2} } \, dx$

= $37\int\limits^1_0 {Cos(x)^{2} } \, dx$

= 37 (0.905620)

M8 = 33.50794

choli [55]

President Reagan’s new approach to the Cold War reveal about his foreign-policy strategy is:

<u>C. He wanted to work for peace from a position of military strength. </u>

<u />

The Cold War was a period in history between the United States and Russia (then known as the Soviet Union) where there were conflicts which led to trade embargoes, diplomatic issues and threats of war.

The two leaders of America and the Soviet Union respectively, President Reagan and Comrade Gorbachev were engaged in war of words and President Reagan tried to make peace and evoid conflict, even though the United States were stronger from a military perspective

Therefore, the correct answer is option C
