Ans:
*Carbohydrates
*Proteins
*Cholesterol
Explanation:
The plasma membrane is a structure that has several distinct roles in the cell
The plasma membrane is mainly composed of the phospholipid Bilayer, which is a layer of two sheets located in the internal and external parts. The Phospholipids are said to be Amphipathic because they have both properties of Hydrophobic and hydrophilic
*The Carbohydrate Molecules attach to the Plasma Membrane such as to the lipids and Proteins:
when They attach to the Proteins, they are known as glycoproteins, and they help in cell recognition, when they attach to the lipids, they are known as Glycolipids
*Protein Molecules play an important role in transport system such as Carrier Proteins
*Cholesterol Molecules help in balancing the Fluidity of the plasma membrane

What do Cl-35 and Cl-36 have in common?
Answer:
they have same atomic number as they are the same element & electrons
Answer: they both have the atomic (proton number) as they are the same element hence they also they have the same number of electrons. Therefore they have similar chemical properties, as the electrons determine the chemical property of an element.
Explanation: The numbers 35 and 37 are the mass numbers for the two isotopes of chlorine. They both have the same atomic number (proton number ) as they are the same

The enthalpy of combustion of 1 mole of benzene is 3169 kJ/mol .
The first step in answering this question is to obtain the balanced thermochemical equation of the reaction. The thermochemical equation shows the amount of heat lost or gained.
The thermochemical equation for the combustion of benzene is;
2 C6H6(l) + 15 O2(g) → 12 CO2(g) + 6 H2O(g) ΔrH° = -3169 kJ/mol
We can see that 1 mole of benzene releases about 3169 kJ/mol of heat.

Why does an atom have a neutral charge?
A It has equal numbers of electrons and protons.
B. The number of neutrons equals the number of protons and
electrons in the atom.
C. It has equal numbers of electrons and neutrons.
D. It has equal numbers of neutrons and protons.
Answer:
option A it has equal numbers of electrons and protons
Explanation:
electrons are negatively charged and protons are positively charged, so if the numbers of each are equal, then the atom will be neutral.
Answer:
A. it has equal numbers of electrons and protons
Explanation:
The overall charge of every atoms is neutral because the number of electrons and protons is the same. Protons are positively charged while electrons are negatively charged and so they cancel out.
Calculate the minimum volume of oxygen gas, at room temperature and pressure(r.t.p). required to completely burn 56g of methane gas. Give your answer to two significant figures. (1 mole of any gas occupies 24 dm³ at r.t.p,Ar:C=12,H=1)
BALANCED EQUATION FOR THE BURNING OF METHANE GAS.
CH₄+2O₂→CO₂+2H₂O
Answer:
170 dm³ (2 significant figures)
Explanation:
CH₄ + 2O₂ → CO₂ + 2H₂O
We need to find how much 'volume' of O₂ is required to burn 56 g of CH₄.
Let's take the ratios of the two gases only.
CH₄ : 2O₂ (in terms of moles the ratio is 1:2)
56g : x dm³
Mr of CH₄ : Volume of oxygen at rtp
Find the Mr of CH₄.
Mr of CH₄ = 12 + (1 × 4) = 16
We know that 1 mole of any gas occupies 24 dm³ at room temperature and pressure (rtp). We have to find the volume of oxygen, there are 2 moles of oxygen, so 2 moles of gas will occupy:
2 × 24 = 48 dm³
56g : x dm³
16 : 48 dm³
16x = 56 × 48
16x = 2688
x = [tex]\frac{2688}{16}[/tex]
x = 168 dm³
∴ the minimum volume of oxygen gas, at room temperature and pressure required to completely burn 56g of methane gas is 170 dm³

for the reaction 2nh3(g)↽−−⇀ 3h2(g)+n2(g), if 15.8 grams of ammonia produced 1.87g of hydrogen, what was the percent yield
Answer:
75%
Explanation:
So, the reaction will consume 1 mole of hydrogen gas and produce
1mole H2⋅2 moles NH33moles H2=0.667 moles NH3
at 100% yield. This represents the reaction's theoretical yield.
Now, you know that the reaction produced 0.50 moles of ammonia. This represents the reaction's actual yield.
In order to find the percent yield, you need to figure out how many moles of ammonia are actually produced for every 100 moles of ammonia that could theoretically be produced.
You know that 0.667 moles will produce 0.50 moles, so you can say that
100moles NH3.in theory⋅0.50 moles NH3.actual0.667moles NH3.in theory=75 moles NH3.actual
Therefore, you can say that the reaction has a percent yield equal to
% yield = 75%

2. The two naturally occurring isotopes of hydrogen are hydrogen-1 ( 1.00783 amu; 99.9885 percent) and hydrogen-2 (2.01410 amu; 0.0115 percent). What is the average atomic mass of hydrogen?
A. 1.0079 amu
b. 1.0097 amu
c. 1.0309 amu
D. 1.5110 amu
Answer:
1.0079 g/mol
Explanation:
99.989% / 100% = 0.99989 hydrigen-1 , 0.0115% / 100% = 0.000115 hydrogen-2
0.99989 x 1.0078 = 1.0077 , 0.000115 x 2.0141= 0.000232
1.0077 + 0.00023

The wavelength is 0.02 m.
Step-by-step explanation:
Given :
[tex]\green\star[/tex] Velocity = 12 m/s[tex]\green\star[/tex] Frequency = 600 HzTo Find :
[tex]\green\star[/tex] WavelengthUsing Formula :
Apply Wavelength formula :

1. Test a sixth liquid to see if it follows patterns in the rest of the data.
2. Use a new thermometer to make sure that the original one was not faulty.
3. Continue collecting data until exact boiling points can be found.
4. Test the results an eleventh time, and average the new trial into the data.
Answer: Test a sixth liquid to see if it follows patterns in the rest of the data.
Explanation:

Temperature measures the average kinetic energy of particles of the substances. Therefore, the correct option is option A. Temperature is a physical quantity.
What is temperature?Temperature is used to measure degree or intensity of heat of a particular substance. Temperature is measured by an instrument called thermometer.
Temperature can be measured in degree Celsius °c, Kelvin k or in Fahrenheit. Heat always flow from higher temperature source to lower temperature source.
We can convert these units of temperature into one another. The relationship between degree Celsius and Fahrenheit can be expressed as:
°C={5(°F-32)}÷9
The boiling points of five liquids have been measured 10 times each by a team of scientists, with fairly consistent results. the next step would be to Test a sixth liquid to see if it follows patterns in the rest of the data.
Therefore, the correct option is option A.
