what form of matter has a definite shape and takes up space?
Answer:
If something is in a solid state of matter, it has a definite shape and volume. The volume of an object is the amount of space it occupies. A block of wood placed on a table retains its shape and volume, therefore, it is an example of a solid. If a liquid is poured on that same table, there are very different results

The specific heat capacity of silver is 0.24 J/g °C. How many joules of energy are needed
to warm 0.500 g of silver from 25.0°C to 27.5°C?
Answer:
0.3 J
Explanation:
The equation for heat capacity is Q = mcΔT where Q is the heat, m is the mass of the substance, c is the specific heat capacity of the substance and delta T is the change in temperature. Plugging those values into the equation, we have Q = (.500)(0.24)(27.5-25) = 0.3

Which of the following would be the evidence of a physical change?
a. change in state of matter
b. precipitate was formed
c. unexpected change in odor
d. formation of bubbles
Answer:
[tex]\boxed {\boxed {\sf A. \ Change \ in \ state \ of \ matter}}[/tex]
Explanation:
A physical change occurs when only the physical properties change. They are generally reversible and no new substances are formed.
However, in a chemical change, the chemical structures and properties change, plus new substances are formed.
Let's analyze each answer choice.
1. Change in state of matter
The state of matter is a physical property, so this is a physical change.
2. Precipitate was formed
A precipitate is a solid formed in a liquid solution. This is a new substance and a chemical change.
3. Unexpected change in odor.
A change in odor is a sign of chemical change.
4. Formation of bubbles
Bubbles signify the formation of gas or a new substance.
So, the best answer choice is A. change in state of matter
Question:

Write the complimentary DNA strand for the given strand of DNA
CGTAAGCGCTAATTA
Answer:
The answer is GCATTCGCGATTAAT
Explanation:
"Chargaff's rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine."
If this is not the answer, try the translation with the 5-3 Strategy and if not still then try using U instead of T.

Explanation:
20g of Na and 10g of Cl2 which is in excess?
The equation of the reaction is given as;
2 Na + Cl2 --> 2 NaCl
From the equation;
2 mol of Na reacts with 1 mol of Cl2
Converting the masses of reactants given to mol
Number of moles = Mass / Molar mass
Na;
Number of moles = 20 / 23 = 0.8696 mol
Cl2;
Number of moles = 10 / 71 = 0.1408 mol
In the chemical equation, the ratio was 2: 1 however with the masses, we can tell that Na is in by far excess.
0.8696 mol of Na would require 0.4348 of Cl2 (Present = 0.1408 mol)
This means;
Na - Excess Reactant
Cl2 - Limiting Reactant
Second part; How much NaCl would be produced?
The limiting reactant determines how much of the product is formed.
From the equation of the reactant;
1 mol of Cl2 produces 2 mol of NaCl
0.1408 mol of Cl2 would require x mol of NaCl
1 = 2
0.1408 = x
x = 0.2816 mol of NaCl
Converting to mass;
Mass = Molar Mass * Number of moles
Mass = 58.44 g/mol * 0.2816 mol
Mass = 16.46 g
