Answer is: acid.
An acid<span> is a </span>molecule<span> or </span>ion<span> capable of donating </span>proton or hydrogen ion H⁺.
pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity <span>an </span>aqueous solution<span>.
</span>pH number of <span>lemon juice (citric acid) and vinegar (acetic acid CH</span>₃COOH) is below seven (pH<span><7). For bases pH is greater than seven.</span>
Answer:
The greater the frequency means the more energy transferred.
The greater the wavelength means the less energy transferred
X4O10
Let molar mass of X be y
molar mass = 4y + 10 x 16 = 4y+160
so, moles = 85.2 / (4y+160)
Moles of oxygen = 10 x [85.2 / (4y+160) ]
Mass of oxygen = 16 x 10 x [85.2 / (4y+160) ]
which is 48.0
so, 48 = 16 x 10 x [85.2 / (4y+160) ]
Solve the equation to get y.
y = 31

Answer: 2232 torr
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 750 torr
= final pressure of gas = ?
= initial volume of gas = 36.0 L
= final volume of gas = 15.0 L
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The pressure will be 2232 torr if the volume changes to 15.0 L and the temperature changes to 78 °C, if the amount of gas stays the same.
