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

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.

How many moles are contained in 127 grams of lead?
Answers
Answer:
18.015
Explanation:
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.
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.

What kind of elements form covalent compounds?
Answers
So some examples of covalent compounds may include:
O2 – oxygen.
Cl2 – chlorine.
H2 – hydrogen
as these all occur between non metals.
Answer:
Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom. In general, ionic bonds occur between elements that are far apart on the periodic table.
