Answer:
Two (2) types of ions
Explanation:
Metal ions (cations) and negatively charged ions (anions) of either chloride, carbonate, sulphides or hydroxides are present during the selective precipitation.
Majorly, the process determines the metal ions present by initiating precipitation as certain conditions.
I hope this was helpful.
Answer:
1. 1.100x10⁴mg
2. 2444mg
Explanation:
1. The 18.00g milk chocolate bar contain 11.00g of sugar. In miligrams:
11.00g * (1000mg / 1g) = 1.100x10⁴mg
2. If a bar of 18.00g contain 11.00g of sugar, a bar of 4.000g will contain:}
4.000g bar * (11.00g / 18.00g) = 2.444g of sugar.
In miligrams:
2.444g * (1000mg / 1g) = 2444mg
Answer:- 88 kPa.
Solution:- The level of mercury in the atmospheric arm that is the open arm is 83 mm. It indicates the gas pressure is 83 mm higher than the atmospheric pressure.
gas pressure = height of mercury level in open tube in mm + atmospheric pressure
Let's convert this 83 mm pressure to kpa since the atmospheric pressure is given in kPa and the answer is also asked to report in kPa.
mmHg is converted to atm first and then atm is converted to kpa.
760 mmHg = 1 atm
and 1 atm = 101.325 kPa

= 11 kPa
Atmospheric pressure is 76.9 kPa.
gas pressure = 11 kPa + 76.9 kPa
gas pressure = 87.9 kPa
If we think about sig figs rule then 87.9 should be round to 88 as in addition we go with least number of decimal places. 11 kPa does not have any decimal places and so the gas pressure is 88 kPa.
Answer:
Explanation:
period:soft metal
group: caesius
family: Alkali
hope this helps i really tried on this one i do know its the
softest metal it basically wax at room temperature
pretty cool
