Answer:
43.2 moles of carbon dioxide are required and 421g of glucose could be produced
Explanation:
Based on the reaction:
6CO2 + 6H2O → C6H12O6 + 6O2
1 mole of glucose, C6H12O6, requires 6 moles of carbon dioxide. 7.2moles of glucose requires:
7.2mol C6H12O6 * (6mol CO2 / 1mol C6H12O6) =
<h3>43.2 moles of carbon dioxide are required</h3><h3 />
618g of CO2 -Molar mass: 44.01g/mol- are:
618g * (1mol / 44.01g) = 14.04moles CO2
Moles C6H12O6:
14.04moles CO2 * (1mol C6H12O6 / 6mol CO2) = 2.34moles C6H12O6
Mass glucose -Molar mass: 180.156g/mol-
2.34moles C6H12O6 * (180.156g / mol) =
<h3>421g of glucose could be produced</h3>
Number of moles = volume / (molar volume)
Molar volume at stp = 22.4 dm^3
Volume = no of moles × molar volume
= 0.987 × 22.4
= 22.1088 dm^3
= 22108.8 cm^3

The Big Bang theory is one of the ones used most frequently nowadays to describe how the cosmos came into being.
<h3>What does big bang theory state?</h3>
According to this theory, the universe formed 13.8 billion years ago as a result of the primordial atom, a single particle, exploding and generating an unprecedented cosmic disaster. The universe is always expanding, according to the same theory.
The key supporting data for the big bang theory are:
The galaxies to getting further and distant from us. This distance is taken at high speeds. In other words, the distance between galaxies is inversely correlated with their spacing velocity. Our perception of galaxy dysthanization occurs because the universe is continually expanding, according to this data, which is known as the "Hubble Law," and this hypothesis also explains that The cosmos has already been unified.
According to the big bang theory, the cosmos was extremely hot at the time of its creation; if this is accurate, we should find some proof of this warmth. Radio astronomers discovered this proof when they noticed that microwaves with a temperature of 2,725 degrees Kelvin included cosmic background radiation. This radiation is perhaps proof of the universe's high temperature.
Last but not least, the Big Bang most likely contributed to the abundance of hydrogen and helium elements.

B. Energy transfer would occur between the copper bars and the surroundings.
Explanation:
In an open system, energy transfer would occur between the copper bars and the surroundings.
There are three types of systems:
- Isolated system in which matter and energy is not exchange with the surrounding.
- Closed system there is no exchange of matter but energy is exchanged with the surrounding.
- Open system: there is exchange of both matter and energy.
If the copper bars were placed in an open system matter and energy will be exchanged with the surrounding.
