6. Which of the following molecules has a central atom with precisely two unshared
pairs of electrons?
methane, CH4
ammonia, NH3
hydrocyanic acid, HCN
water, H20
CLEAR ALL
Answer:
water, H20
Explanation:
From the given choices, only water has two unshared or lone pairs of electrons in its central atom.
The formula of water is:
H₂O
H is hydrogen with 1 electron
O is oxygen with 8 electrons and 6 valence electrons
To form the covalent bond, the 6 valence electrons are involved. Two out of the 6 bonds with the two oxygen.
The remaining 4 gives the two lone pairs.
How many grams are there in 4.30 x 10²⁶ molecules of H₂SO₄?
Mass of H₂SO₄ : 69,972 g
Further explanationA mole is a number of particles(atoms, molecules, ions) in a substance
This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
moles of H₂SO₄ :
[tex]\tt mol=\dfrac{N}{No}\\\\mol=\dfrac{4.3\times 10^{26}}{6.02\times 10^{23}}\\\\mol=7.14\times 10^2[/tex]
mass H₂SO₄ (MW=98 g/mol) :
[tex]\tt mass=mol\times MW\\\\mass=7.14.10^2\times 98\\\\mass=69,972~g[/tex]
4. How does the
productivity of
photosynthesis affect the
productivity of cellular
respiration?
Answer: it’s the chemicals between the biological
Explanation:
The productivity of photosynthesis affect the productivity of cellular respiration by providing energy.
What is photosynthesis?Photosynthesis is a process where plants prepare their food in the presence of sunlight.
Photosynthesis process chemically illustrated as :
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
From the above it is clear that carbohydrate is produced in the photosynthesis process and this carbohydrate provide energy to the plant for the completion of another chemical process. So, for the cellular respiration plants use this energy.
Hence, the productivity of photosynthesis directly affect the productivity of cellular respiration.

A. matter
B. solid
C. liquid
D. gas
Answer:
solids
Explanation:
Solid is A substance with definite volume and shape. Solids do not flow and therefore do not conform to the shape of their containers. Liquid - A substance with definite volume but without definite shape

Explanation:
Many plants in rainforests have leaf tips that come to a point, so precipitation drains off the leaf. This helps to keep the plant safe from harmful germs. Based on this info, what resource is prevalent in a rainforest?
Answer:
rainfall/water
Explanation:
The possession of drip tips by the leaves of plants in the rainforest is a form of adaptation against high rainfall. Without the drip tips on leaves, water will persist on the surface of leaves, and in conjunction with the warm climate, promotes the growth of pathogens such as fungi and bacteria.
Hence, the possession of drip tips on leaves is an indication of the prevalence of water in the rainforest region.
What is Newton's 1-3rd laws of motion? Give examples for each
Answer:
In the first law, an object will not change its motion unless a force acts on it
In the second law, the force on an object is equal to its mass times its acceleration
In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Compute the number of ions in 58.5 g oh nacl
Answer: Explanation:
58.5 g of Na Cl = 1 mole 5.85 g ofNaCl = 1 X 5.85/58.5 = 0.1 mole Each molecule of NaCI contains one Na ion and one Cl ion = 2 ions Total moles of ions in 0.1 mole of NaCI = 2 x 0.1 = 0.2 moleshow many moles of oxygen molecules can be produced from 6 moles of lead oxide
Answer:
Moles of oxygen molecules produced = 3 mol
Explanation:
Given data:
Moles of oxygen molecules produced = ?
Number of moles of lead oxide decomposed = 6 mol
Solution:
Chemical equation:
2PbO₂ → 2PbO + O₂
Now we will compare the moles of oxygen and lead oxide.
PbO₂ : O₂
2 : 1
6 : 1/2×6 =3 mol
three moles of oxygen molecules are produced.

Many of the lunar craters are due to volcanic eruptions true or false
Answer:
false
Explanation:
Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. ... It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.

b) sodium hydroxide (lye)
Explain why it should be used
Sodium hydroxide, with the formula NaOH, is usually used in products as a pH adjuster. It's also used in soap-making to turn fats and oils into soap. You can find sodium hydroxide (also called caustic soda or lye) in its pure form in the cleaning aisle, since it's also really handy for clearing up clogged drains.

Answer:
6O₂
General Formulas and Concepts:
Chemistry/Biology
Photosynthesis Equation: 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂Explanation:
Most of the equation comes from the Photosynthesis Equation. Plants take in water and carbon dioxide and sunlight (energy) to produce glucose and oxygen. When we balance the equation and predict reaction. we should get 6O₂ as our answer.
Which of the following best describes the relationship between the speed of sound and the type of medium?
A.
Sound travels slower in air because of the large distance between air particles
B.
Sound travels slower in solids because of the small distance between solid particles
C.
Sound travels slower in air because of the small distance between air particles
D.
Sound travels slower in solids because of the large distance between solid particles
Answer:
A. Sound travels slower in air because of the large distance between air particles
Explanation:
Sound is a mechanical wave that requires a medium for its propagation. Without a medium, sound cannot go through easily or readily. This implies that sound cannot be propagated through a vacuum.
A vacuum is an empty space without any particles in side. Sound waves travel fastest the most in solids because the particles are dense and close to one another. The speed of sound in air is the least because of the large distance between air particles. Therefore, the speed of sound is medium dependentThe diagram below shows the energy conversions of the Krebs cycle, which is part of cellular respiration. The U-shaped

Which of the following properties would a substance that has metallic bonding
normally have?
I. thermal conductivity
II. electrical conductivity
III. malleability
IV. ductility
Answer:
I, II, III,IV
Explanation:
Metals are known to possess metallic bonds. In a metallic bond, electro-positive metals loose electrons which form a cloud of electrons which exerts an attractive force on the positive metallic ions. This attractive force holds the metal atoms together in the crystal lattice.
The physical properties of metals include;
I. thermal conductivity
II. electrical conductivity
III. malleability
IV. ductility
Hence, substances that exhibit properties I-IV are metals and have metallic bonds.
The following properties which a substance that has metallic bonding
normally have include
