Chemistry

1 answer:

AveGali [126]1 year ago

8 0

Answer:

1) represented by a lower case letter
2) always masked by dominant genes

3) only expressed in the absence of a dominant gene

Explanation:

So if I take a black and a yellow marker- and tried drawing the yellow over the black- or the other way around- you'd still only see the black marker. The recessive trait is like the yellow marker. Now if I drew the yellow marker with another yellow marker you would see the yellow. I hope this helps!

Natalija [7]

Answer:

625=275

240=x

625x=275×240

625x=66000

x=66000/625

x=105 .6

Explanation:

If 625°C gives us 275KPa then 240°C will give us the the sum of 275×240 divided by 625

The following equation shows the equilibrium in an aqueous solution of ammonia: NH3(aq)+H2O(l)⇌NH4+(aq)+OH−(aq)NH3(aq)+H2O(l)⇌NH

yarga [219]

Answer:

c) H2O and OH−

Explanation:

Acids are the species which furnish hydrogen ions in the solution or is capable of forming bonds with electron pair species as they are electron deficient species.

When an acid donates a proton, it changes into a base which is known as its conjugate base.

Bases are the species which furnish hydroxide ions in the solution or is capable of forming bonds with electron deficient species as they are electron rich species. When a base accepts a proton, it changes into a acid which is known as its conjugate acid.

The acid and the base which is only differ by absence or presence of the proton are known as acid conjugate base pair.

Thus, for the reaction,

$NH_3+H_2O\rightleftharpoons Nh_4^++OH^-$

The base is $NH_3$ and the conjugate acid of the base is $NH_4^+$ .

Also, The base is $OH^-$ and the conjugate acid of the base is $H_2O$ .

Correct option is :- c) H2O and OH−

650.J is the same amount of energy as? 2720cal 1550cal 650.cal 2.72cal

Oksi-84 [34.3K]

Ans: 650 J = 155 calories

Given:

Energy in joules = 650 J

To determine:

The energy in calories

Explanation:

1 joule = 0.2388 calories

Therefore, 650 joules = 0.2388 calories * 650 J/1 J = 155 calories

How can you described the energy of a storm

lakkis [162]

Answer:

When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. If wind conditions are right, the storm becomes a hurricane. This heat energy is the fuel for the storm.

Develop a demonstration to show how weight is not the same thing as mass

maksim [4K]

Answer with Explanation:

"Mass" and "weight" should never be used interchangeably with each other. Mass refers to the total amount of matter that can be measured in an object, while weight refers to the measure of the force of gravity that is acting on the object's mass.

The mass of an object is constant (meaning, it doesn't change even if the object will be placed on another location) while the weight of an object relies on the force of gravity. So, this means that your mass on Earth and on the moon are identical, however, your weight on Earth and on the Moon are different. You will weigh lesser on the Moon because it has a lesser surface gravity than that of Earth.

So, this explains the answer.
