Which type of energy uses the photoelectric effect?

Biomass
Solar
Geothermal
Wind

Answers

Answer 1

Answer:

My lovely people the answer is SOLAR

Explanation:

i just know

Answer 2

The type of energy that uses the photoelectric effect is solar energy. Therefore, the correct option is option B.

When light strikes a material surface, the photoelectric effect takes place, which results in the emission of electrons. Albert Einstein made this intriguing discovery in 1905, and it was essential in the development of quantum physics and our comprehension of the nature of light. The fundamental principle underlying the photoelectric effect is that light is made up of small energy packets known as photons. A photon's energy can be transferred to an electron in a solid or atom when it interacts with those structures. The type of energy that uses the photoelectric effect is solar energy.

Therefore, the correct option is option B.

How many moles are contained in 127 grams of lead?

Answers

Answer:

18.015

Explanation:

Answer: 0.613 moles

Explanation: To convert from grams to moles, you have to use the molar mass provides on the periodic table. The molar mass of lead is 207.2 g/mol. To find the moles, we need to divide the grams of lead by the molar mass. 127/207.2 is equal to about 0.613 moles.

The Story Behind The Snowy Sour
As the air gets cooler and winter creeps in, I’m looking forward to the first snowfall of the season. This cocktail is all you will need to help you through. I took a classic sour cocktail and elevated it with a winter-citrus-infused simple syrup, made by combining clementine, orange, and honey with sugar and water. All the flavors came together really well, and the gin and fresh lemon juice amalgamate beautifully.

Ingredients In The Snowy Sour:

1.5 ounces gin
1 ounce lemon juice
¾ ounce winter citrus syrup
1 egg white
Snowy Sour Directions:

Combine all ingredients in a cocktail shaker with ice.
Shake hard to chill and combine.
Strain out ice.
Shake hard again to create a silky consistency.
Finely strain into your cocktail glass.

A plant uses the energy from sunlight to create oxygen and glucose from carbon dioxide and water which statement is true about the changes that have occurred

Answers

Answer:

The correct answer choice is A. A chemical change has occurred because new compounds have been produced.

Explanation:

A physical change is defined as a change in which there is alteration in shape, size etc. No new substance gets formed in these reactions.Example: Melting of ice A chemical change is defined as a change in which a change in chemical composition takes place. A new substance is formed in these reactions.Example: photosynthesis

Photosynthesis is the process used by plants, algae and certain bacteria to convert energy from sunlight and turn it into chemical energy in the form of glucose which is used a s a source of energy by many organisms.

Thus the true statement is a chemical change has occurred because new compounds have been produced.

A chemical reaction produces formaldehyde, with a chemical formula of CH2O. Carbon is in Group 4A, oxygen is in Group 6A, and hydrogen is in Group 1A on the periodic table. In one to two sentences, describe the bonds in a molecule of formaldehyde in terms of valence electrons.(2 points)

Answers

This problem is providing a comparison on the atoms forming formaldehyde, CH₂O, in terms of the groups they are in, C in group 4A, O in group 6A and H in group 1A, and it is asking for a description about the bonds once they are bonded in a formal Lewis dot structure.

In such a way, the attached file shows the Lewis dot structure, in which we can find two bonds between the two hydrogen atoms and the carbon one, and also, a double bond between carbon and oxygen.

The aforementioned is explained by bearing to mind the concept of octet, which states that elements in groups 4A, 5A, 6A and 7A are able to complete 8 valence electrons after bonding.

Thus, since carbon is in group 4A we infer it needs 4 more electrons to complete the octet, and that is achieved due to the 4 bonds it is having with the two hydrogen atoms and double bond with the oxygen atom.

In addition, since oxygen is in group 6A, we infer it needs two more electrons to complete its octet, which is attained via the double bond it has with the carbon atom. For hydrogen, however, it can complete one bond at maximum, because it is in group 1A, which means it can complete two valence electrons after bonding.

A compound has the following percentage composition: 40.0% carbon, 6.72% hydrogen, 53.28% oxygen. What is the amount of carbon moles in 200g of the compound?

Answers

Answer:

So we're trying to find the number of carbon moles in the compound. We know that we have 200g of the compound and that 40% of it is Carbon. and 40% of 200 is 80g (change 40% into a decimal and multiply it by 200 and you get 80g)

So 80g of the compound is carbon. In order to find the moles of Carbon, I have to divide the mass by the molar mass of the element.

We know from our periodic table that the molar mass for carbon is 12g/mol

[tex]\frac{80}{12} = 6.67\ mol[/tex]

Therefore we have 6.67 moles of carbon in the compound

Answer:

6.67 moles of carbon in compound
