The mass will not change, because if you add or subtract any clay the mass doesn't change if u took some away or added any the mass would have changed.
Distance has a physical quantity which has been measured in meter. If a man travel then it will measured in meters that shows that how much he had travelled from one place to another place for all such type of things we use to measure the distance.
Centimeter is also been physical quantity which has to be used measure distance. 1 centimeter is just equal to 0.01 meter and 1 centimeter is just equal to 0.00001 kilometer and the kilometer has been large quantity to measure distance on the other hand centimeter is smaller quantity in which distance is measured.
Kilometer is also known as physical quantity which used to measure the distance of 1 kilometer which is equal to 1000 meter and 1 kilometer is just equal to 10,0000 centimeter.
For above conclusion, we easily states that the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance. Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.
Therefore,The mass will not change, because if you add or subtract any clay the mass doesn't change if u took some away or added any the mass would have changed.

Answer:
Mass percent of N2H4 in original gaseous mixture = 31.13 %
Explanation:
Given:
Initial mass of gaseous mixture = 61.00 g
Initial mole of oxygen = 10.0 mol
Moles of oxygen remaining after the reaction = 4.062 mol
Moles of oxygen used = 10.0 - 4.062 = 5.938 mol
Total oxygen used in both the reactions = 10.0 parts
out of 10 parts, 3 part react with N2H4.
Now, consider the reaction of N2H4
3 moles of O2 react with 1 mole of N2H4
1.78 moles of oxygen will react with 1.78/3 = 0.5933 mol of N2H4
Molecular mass of N2H4 = 32 g/mol
Total mass = 61.0 g
The mass percent of N2H4 in the gaseous mixture can be determined through stoichiometric calculations and determining the limiting reactant. The initial and remaining amounts of O2 are used to calculate the reacted amount of O2, which then allows for the calculation of the amount of N2H4. This information is used in the mass percent formula.
The balanced reaction states that for one mole of NH3, one mole of O2 is required, while for one mole of N2H4, 3 moles of O2 are required. Thus, the initial moles of O2 were 10 moles and after reaction 4.062 moles O2 remained. Thus, the reacted amount of O2 is 10 - 4.062 = 5.938 moles. From calculating the limiting reactant and applying stoichiometry, the amount of N2H4 can be determined. We know the molar mass of N2H4 is 32 g/mole. By calculating the molar ratio, we can then calculate the mass percent of N2H4 in the mixture using the formula: (mass of N2H4 / total mass) * 100%.

Answer: Position 1
Explanation:
Seasons on Earth occur due to tilt of of its axis. Earth's axis is tilted 23.5° from horizontal. Thus, when Earth moves in the orbit around sun, sometimes the northern hemisphere points towards the Sun and sometimes away. When it points towards the Sun, it experiences Summer season and while it points away, winter occurs. In between, spring and autumn occur.
Thus, from the given diagram, norther hemisphere would have summer time at position 1 when the northern hemisphere is facing the Sun.
Answer:
The correct answer is Position 1.
Explanation:
The rotational motion of the Earth causes some parts to receive more heat from the sun, while others receive less. Its axis of rotation runs vertically from the North Pole to the South Pole. Since this axis is not completely vertical, the sun's rays are projected with different intensity during the translation movement. Since the Earth is tilted slightly to the left and the axis points to the side where the Sun is at position 1, the sun's rays reach the northern hemisphere with more intensity and the southern hemisphere with less intensity.
Have a nice day!
