350 mL = 0.350 L
245.0g H2SO4 / 98.08 g/mol H2SO4
= 2.5 mol H2SO4
2.5 mol H2SO4 / 0.350 L = 7.14 M
Renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel) does not contribute carbon dioxide (CO2) emissions to the atmosphere, unlike fossil fuels (coal, oil and natural gas).
Answer: The most abundant gas in the atmosphere is nitrogen.
Explanation:
The Earth’s atmosphere is composed of approximately 78 percent nitrogen, 21 percent oxygen, 1 percent argon and trace amounts of other gases that include carbon dioxide and neon.
An atom is the smallest unit of matter that has the properties of an element. It is composed of a dense core called the nucleus and a series of outer shells occupied by orbiting electrons. The nucleus, composed of protons and neutrons, is at the center of an atom.
Explanation:
Answer:
The rate of heat transfer in cooler A is lower than the rate of heat transfer in cooler B and more heat energy is being transferred in cooler B than in cooler A.
Explanation:
A person packs two identical coolers for a picnic, placing twenty-four 12-ounce soft drinks and 5 pounds of ice in each. However, the drinks put into cooler A were refrigerated for several hours before they were packed in the cooler, while the drinks put into cooler B were at room temperature.
Therefore, the drinks in cooler A are at lower temperatures than those in cooler B because the drinks in cooler A have been refrigerated for several hours.
Generally when there is temperature gradient in a system, heat energy will flow from the body at high temperature to the body at low temperature until thermal equilibrium is reached.
The rate of heat transfer in cooler A is lower than the rate of heat transfer in cooler B and more heat energy is being transferred in cooler B than in cooler A. As a result, majority of the ice in cooler B has melted while there are still more ice in cooler A.
