6.23L volume of h2 gas is produced at stp.
<h3>How do you calculate the H2 gas volume?</h3>
Given that one mole of dihydrogen (H2) weighs 2,0159 g/mol, the experimental density of hydrogen—which is 0,0899 g/L at 0 °C and 0,0837 g/L at 20 °C—can be used to compute the exact molar volume of hydrogen.
<h3>How do you calculate the H2 gas volume at STP?</h3>
This implies that at STP, one mole of hydrogen also takes up 22.4 liters of space. Therefore, at STP, 10moles of hydrogen gas will take up =22.410=224litres of space. In other words, when 460g of salt combines with extra water at STP, 224litres (or 224000mL) of hydrogen gas are released.

the question you are looking for is
A 5.00 g sample of Al reacts with excess H2SO4. What volume of H2 gas is produced at STP?
2Al(s) + 3H2SO4(aq)→ Al2(SO4)3(aq) + 3H2 (g)
Answer:
Plant Cells
Explanation:
They are plant cells because of the rectangular structure. Animal cells look 'uglier'.
Answer:
B. Density
Explanation:
Density is the only property of liquid in the option that is feasible.
Water has no form of magnetism as it’s not a magnetic substance.
Water carries the size of the container it is put into and has no definite shape.
Water’s boiling point can only be gotten when it’s heated and it’s known to be mostly 100 degree celsius when pure and may be more or less depending on the level of impurities.
However Density is the mass per volume of water and can be calculated before the noodle is cooked which is more effective in its differentiation.

Hope this helped :)
Your speed is increased by 5 m/s in 2 seconds, so your acceleration is 5/2=2.5 m/s/s, or 2.5 metres per second squared.
