Answer: 159.61 g/mol
Copper has a molar mass of 63.546 g/mol
Sulfur has a molar mass of 32.065 g/mol
Oxygen has a molar mass of 16 g/mol, multiply by 4 and it is 16 x 4 = 64 g/mol
63.546 + 32.065 + 64 = 159.61 g/mol
Idk to explain this but the answer is Solid...i think...
Entropy is a measure of chaos or disorder in a system. For the first one, the system with the highest entropy is a cup of water at 0 degress centigrade. For the second question, the system with the lowest entropy is sugar crystals in 95 degrees centigrade cup of coffee.
<span>In water, naoh almost completely separates into na+ and oh- ions. thus, naoh is Stong base.
Strong bases and strong acids completely ionized in the water,So when NaOH is added into water, it is completely ionized and forms Na+ and OH- ions and it shows that it is a strong base.</span>
Answer:
6
Explanation:
Significant figures:
The given measurement have six significant figures 120.090.
All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.
Leading zeros are not consider as a significant figures. e.g. 0.03 in this number only one significant figure present which is 3.
Zero between the non zero digits are consider significant like 104 consist of three significant figures.
The zeros at the right side e.g 2400 are also significant. There are four significant figures are present.
In 120.090 the zero before and after 9 are also significant.
