Many of the lunar craters are due to volcanic eruptions true or false

Answers

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.

Which of the following statements is FALSE about the diagrams above?
Diagram B is a mixture of compounds.
Diagram C is a pure substance of a diatomic element.
Diagram D is a mixture of elements and compounds.
Diagrams A&C represent a pure substance of elements.
14 15

Answers

Answer:

Diagram B is a mixture of compounds

Explanation:

The false statement about any of the diagram is that diagram B is a mixture of compounds.

Diagram is not a mixture of compounds. It is a single compound in gaseous state .

A compound is a combination of elements in a definite grouping. The properties of the compound is distinct from that of the element that combines to form it. Therefore, since we just a black and yellow circle, the diagram is a compound and nothing more. The other descriptions are perfect.

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

Answers

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.

what should we use in soap making process:-
a) potassium hydroxide
b) sodium hydroxide (lye)

Explain why it should be used

Answers

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.

What is the balanced equation for KOH+CO2—>K2CO3+H2O

Answers

The balanced equation :

2KOH+CO₂⇒K₂CO₃+H₂O

Further explanation

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product

3. Select the coefficient of the substance with the most complex chemical formula equal to 1

Reaction

KOH+CO₂⇒K₂CO₃+H₂O

give coeffiecient

aKOH+bCO₂⇒K₂CO₃+cH₂O

make equation

K, left=a, right=2⇒a=2

H, left=a, right=2c⇒a=2c⇒2=2c⇒c=1

O, left=a+2b, right=3+c⇒a+2b=3+c⇒2+2b=3+1⇒2b=2⇒b=1

the equation becomes :

2KOH+CO₂⇒K₂CO₃+H₂O

Both have their advantages and disadvantages. Farmers' markets have fresh and local produce, and often you get a chance to meet the people who grow your food. This isn't the case with grocery stores, where you'll never get to meet the farmers. Grocery stores are starting to have more local products, though, and they have a better variety of goods. Another thing to consider is the setting itself. Farmers' markets are usually in more pleasant, open-air locations where there's often live music playing. Grocery stores, on the other hand, can be busy and uncomfortable if you don't like shopping. The pleasant atmosphere comes at a price, though, as your bill at a farmers' market is likely to be 25 percent more than at a grocery store. All in all, the freshness and quality of food is worth a little more money. Farmers' markets are the way to go. Thanks!!
