An object with a mass of 3.2kg has a force of 16.3 newtons to the right and 6.7 newtons to the left applied to it. What is the r

Pepsi [2]

Answer:

3m/s²

Explanation:

Given parameters:

Mass of object = 3.2kg

Force to the right = 16.3N

Force to the left = 6.7N

Unknown:

Acceleration of the object = ?

Solution:

To solve this problem, we use newtons second law of motion;

Net force = mass x acceleration

Net force on object = Force to the right - Force to the left

Net force = 16.3N - 6.7N = 9.6N

So;

9.6 = 3.2 x a

a = $\frac{9.6}{3.2}$ = 3m/s²

Write a balanced half-reaction for the reduction of bismuth oxide ion to bismuth ion in basic aqueous solution. Be sure to add p

Butoxors [25]

Answer:

$3H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+6OH^-$

Explanation:

Hello there!

In this case, according to the required half-reaction, we start by setting it up from bismuth (V) oxide ion to bismuth (III) ion:

$BiO_3^-\rightarrow Bi^{3+}$

Thus, next realize that the oxidation state of Bi in BiO3^- is 5+ because oxygen is 2- (-2*3+x=-1;x=-1+6;x=+5), so we obtain:

$(Bi^{5+}O_3)^-\rightarrow Bi^{3+}$

Thereafter, we realize three water molecules are needed on the right in order to balance the oxygens and consequently 6 hydrogen atoms on the left to balance hydrogen:

$6H^++(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+3H_2O$

Now, since the balance is is basic media, we add six molecules of hydroxide ions in order to produce water with the hydrogen ones:

$6OH^-+6H^++(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+3H_2O+6OH^-\\\\6H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+3H_2O+6OH^-\\\\6H_2O-3H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+6OH^-$

Then, we accommodate the waters to obtain:

$3H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+6OH^-$

Best regards!

The turnover number is defined as the maximum number of substrate molecules that can be converted into product molecules per uni

Nataliya [291]

Answer:

Explanation:

turn over number = R max / [E]t = K2

From given , R max = 249 * 10 ^ -6 mol. L^-1

T [E]t = 2.23 n mol. L^-1

= 2.23 * 10^-9 mol. L^-1

Putting values in above equation,

= 111.65 * 10^3 S^-1

Turn over number is maximum no of substrate molecule that can be converted into product molecules for unit time by enzyme molecule.

Which of the following processes are physical changes? Mark all

stich3 [128]

The process that is physical changes is:

mixing frozen orange juice concentrate with water

<h3>What is a physical change?</h3>

A physical change can be described as a type of change that take place in physical without chemical reaction as opposed to chemical change.

They are changes that are usually reversible it should be noted that physical change do not involve the alterations as regards the chemical make up of a particular substance and as a result of this , in physical change, there is no formation of new product.

Therefore, The process that is physical changes is mixing frozen orange juice concentrate with water
