Answer:
Gallium, Germanium, Arsenic, Selenium, Bromine and Krypton
Explanation:
Based on periodic trends, the atom that has a larger ionization energy than calcium are Gallium, Germanium, Arsenic, Selenium, Bromine and Krypton.
Across the period, the ionization energy increases from left to right.
- Ionization energy is the energy required to remove the most loosely held electron within an atom.
- As you go from left to right, the ionization energy increases rapidly.
- The elements to the right of Ca will have a higher ionization energy compared to Ca.
Answer:
6.50M
Explanation:
Molarity, M, is an unit of concentration widely used in analytical chemistry. Is defined as the ratio between the moles of solute (In this case, 5.46 moles) and liters of solution. To solve this question we must find the volume of the solution in liters in to find the molarity of the solution, as follows:
<em>Liters solution:</em>
840mL * (1L / 1000mL) = 0.840L
<em>Molarity:</em>
5.46moles / 0.840L
<h3>6.50M</h3>
Answer:
Explanation: A cubic centimetre (or cubic centimeter in US English) (SI unit symbol: cm3; non-SI abbreviations: cc and ccm) is a commonly used unit of volume that corresponds to the volume of a cube that measures 1 cm x 1 cm × 1 cm.
Answer:
a
Explanation:
it would be the most reasonable
Molar mass CO2 = 12 + 16 x 2 => 44.0 g/mol
1 mol ----------- 44.0 g
2.1 mol --------- ( mass CO2)
mass CO2 = 2.1 x 44.0 / 1
mass CO2 = 92.4 / 1
= 92.4 g of CO2
hope this helps!
