Answer:
43.2 g of table salt occupies 20.0 cm2of space- Appropriate for calculating density
150 g of iron density of iron 79.0 g/cm3- Appropriate for calculating volume
21.0 mL of methanol density of methanol 0.79g/mL - Appropriate for calculating mass
3.00 g of white pine, density of white pine 0.40 g/cm3- Appropriate for calculating volume
5.00 cm,3 of table salt weighs 10.8g-Appropriate for calculating density
Explanation:
Density is defined as mass per unit volume. Hence in science;
Density= mass/volume
When mass and volume are both given, the information can be used to determine the density of a given substance.
When volume and density are both given, the information can be used to determine the mass of a given substance.
When the mass and density of a substance are both given, the information can be used to determine the volume of the substance.
Hence the answers given above.
Salted butter does not need to be stored in the fridge since the risk of bacterial growth is so low. ... However, it will stay fresh longer if it is kept in the refrigerator. Refrigeration slows down the process of oxidation, which will eventually cause butter to go rancid.
I hope this helps!
Answer:
The Dry pressure of the gas = 725.9 torr
Explanation:
Total barometric pressure = 749.7 torr
Vapour pressure of water = 23.8 torr
The total pressure is = Vapour pressure of water + Dry pressure of the gas
749.7 = 23.8 + Dry pressure of the gas
Dry pressure of the gas = 749.7 - 23.8
Dry pressure of the gas = 725.9 torr
Therefore the Dry pressure of the gas = 725.9 torr
Answer is: chromium (Cr).
Chromium with atomic number 24, it means it has 24 protons and 24 electrons.
Electron configuration of chromim atom: ₂₄Cr 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵ 4s¹.
In chromium, half full d-sub level (3d) is more stable than a partially filled d sub-level (3d⁴), thai is why an electron from the 4s orbital goes to a 3d orbital.
