Answer:

<h2>4. dominant negative</h2>

Explanation:

Mutation is the process in which sudden changes take place within the sequence of amino acids that causes different type of problems. On the basis of nature and conditions mutation can be classified as dominant negative, neomorphic and some others types. Dominant mutation is also called as antimorphic mutation and changes the functions of the  molecules that are proteins.

What is the sum of the coefficients in the balanced chemical equation for the combustion of acetone, c3h6o(l), in air?
WITCHER [35]

The sum of the coefficients in the balanced chemical equation for combustion of acetone C3H6O in air  is 11

explanation

<h2>write a balanced chemical equation  for reaction</h2>

that is;  C3H6O + 4O2  → 3CO2 +3H2O

coefficient is the number in front of the chemical formula

the sum of coefficient is therefore= 1 ( in front of C3H6O) + 4 ( in front of O2) + 3 ( in front of CO2) + 3 ( in front of H2O) = 11

A sample of coal has the following analysis (wt %). Moisture 1.1%, Fixed Carbon 74%, Volatile Matter 17.9%, Carbon 63.7%, Hydrog
pogonyaev

Answer:

Coal is a traditionally used source of energy, there are main four types of ranks for coal. Here the rank of a coal means to a natural process called Coalification, which takes place during a plant is buried and changes to a harder, and denser material and become even more rich in carbon contents.

Anthracite is know to have the highest ranked coal, it contains highest percent of fixed carbon and lowest percent of volatile material.

PLEASE HELP ME
BabaBlast [244]

Answer:47.05% is the percent yield of nitrogen in the reaction.

Explanation:

heoretical yield of nitrogen gas = x

Moles of ammonia =  

According to reaction,2 moles of ammonia gives 1 mol of nitrogen gas.

Then 2.3529 mol of ammonia will give:

of nitrogen gas

Mass of 1.1764 moles of nitrogen gas,x = 1.1764 mol × 28 g/mol=32.94 g

Experiential yield of nitrogen gas = 15.5 g

Percentage yield:

hope that help

47.05% is the percent yield of nitrogen in the reaction.

How many moles of gas would occupy a 25.0 liter when the temp is 22.0 degrees celsius and the pressure is 646 torr
Luda [366]

Answer:

0.877 mol  

Step-by-step explanation:

We can use the<em> Ideal Gas Law </em>to solve this problem.

pV = nRT     Divide both sides by RT

 n = (pV)/(RT)

Data:

p = 646 torr

V = 25.0 L

R = 0.082 06 L·atm·K⁻¹mol⁻¹

T = 22.0 °C

Calculations:

(a) <em>Convert the pressure to atmospheres </em>

p = 646 torr × (1 atm/760 torr) = 0.8500 atm

(b) <em>Convert the temperature to kelvins </em>

T = (22.0 + 273.15) K = 295.15 K

(c) <em>Calculate the number of moles </em>

n = (0.8500 × 25.0)/(0.082 06 × 295.15)

  = 0.877 mol
