Answer:
it would be in the keyhole probably
Explanation:
Because you would have to put the screwdriver inside to try and break the lock
The mass of the solid product of the reaction is determined by weighing.
Answer:
New volume = 105.6 mL
Explanation:
Given that,
Temperature, T = 240.0 K
Pressure, P = 670 mm Hg
Volume, V = 128 mL
New temperature = -75°C = 198 K
We need to find the new volume. Let it is V'. The relation between volume and the temperature is given by :
So, the new volume is equal to 105.6 mL.
For each element, a square on the standard periodic table will contain:
The Atomic Number (the integer at the top, which represents the number of protons in the atoms of that element)
The Chemical Symbol of the element (the one or two letter symbol, such as C for Carbon, Mg for magnesium)
The Atomic Mass of the element (the average mass of all naturally occurring isotopes of that element. It's often a decimal number because it's an average, even though it represents the number of protons and neutrons in the atom)Usually, the element's common name is listed, but not all charts do this.

There are 6 electrons in the atom of a carbon.
The first atomic level will be occupied by 2 electrons while the second will be occupied by 4 electrons.
Based on this, the outer valence shell of carbon (which is L shell) will be occupied by 4 electrons.
