Given the reaction:NH3 + HCl --> NH4Cl
In this reaction, ammonia molecules (NH3) act as a base because they
(1) accept hydrogen ions (H+)
(2) accept hydroxide ions (OH-)
(3) donate hydrogen ions (H+)
(4) donate hydroxide ions (OH-)

Answers

Answer 1

Answer: The ammonia molecule accepts the hydrogen ions.

Answer 2

Answer:

Answer:

1. accept hydrogen ions (H+)

Explanation:

In the given reaction, NH3 acts as a base because it accepts hydrogen ions (H+) from the acid HCl to form the conjugate acid NH4+. Therefore, the correct answer is 1. accept hydrogen ions (H+).

The percentage by mass of Br in the compoundAlBr3 is closest to
(1) 10.% (3) 75%
(2) 25% (4) 90.%

Answers

Answer: The correct answer is option(4).

Explanation:

Molar mass of the aluminium bromide, $AlBr_3=266.69 g/mol$

Atomic mass of bromine = 79.90 g/mol

Percentage of Mass of bromine in $AlBr_3$ :

$\% Br\text{ by mass}=\frac{\text{Atomic mass of Br}* \text{Number of Br atoms}* 100}{\text{Molar mass of }AlBr_3}$

$\% Br\text{ by mass}=(79.90 g/mol* 3* 100)/(266.69 g/mol)=89.97\%\approx 90\%$

Hence, the correct answer is option(4).

What you have to do it find the percentage / solve it. Divide the mass by the entire mass.
239.7 ÷ 266.68 = 0.898 × 100 = 90% Br.

Green plants need light in order to survive Structures in the leaves absorb light, which in turn, helps plants make theirown tood
Under which color of light will plants be least likely to make food?
red
blue
orange
green

Answers

Answer:

The color of light in which plants are less likely to produce food is green.

Explanation:

Photosynthesis is the process by which plants take advantage of sunlight to convert it into chemical energy, necessary to manufacture their nutrients, their growth and development.

Plants do not absorb all the colors of the light spectrum, since due to their pigments they absorb colors with specific wavelengths. Green plants do not absorb the color green, but reflect it —due to the chlorophyll pigment— which gives the green color to those leaves.

For this reason, the light that plants take least advantage of to produce food is green light.

Other options:

The colors blue, orange and red can be absorbed by the plant, to a lesser or greater degree.

Answer:

it would be green

Which of the following is an extremely reactive family of elements?a. noble gases
c. carbon family
b. halogens
d. metalloids

Answers

Answer:

b. Halogens

Explanation:

Chemical reactions are associated with the 'breaking' of old bonds and formation of new bonds. Since valence electrons are the ones that participate bonding, therefore the reactivity of elements must depend on the ease with which these electrons can be lost or gained.

Noble gases have fully filled (n²np⁶) valence electron configuration and are highly stable and inert.

Carbon family have less that half filled p-orbitals (ns²np²) in their valence configuration and are not very reactive. Metalloids have their reactivity in between metals and non-metals.

Halogens in contrast have a valence electron configuration of ns²np⁵. They only need one more electron to complete their octet and become stable. As a result they are highly reactive i.e. they readily attract electrons and form new bonds.

The halogens are extremely reactive, because they only need ONE MORE valence electron till they become stable, meaning they would bond and be very reactive.

A substance whose shape can easily change is aa. solid.
b. powder.
c. fluid.
d. metal.

Answers

Answer:

The correct answer is the option:

c. fluid.

Explanation:

Hello!

Let's solve this!

A substance that can change its shape quickly is a fluid. Fluids have the property of adapting to the shape of the container that contains them. So you can easily change shape.

After the explanation, we conclude that the correct answer is the option:

c. fluid.

c. fluid
Fluids, like water for example, can quickly change shape and conform to their surroundings.
