What is the name of the covalent compound CCl4?

Chemistry
1 answer:
zubka84 [21]3 years ago
4 0
Think, first, about the type of molecule or formula unit you have (covalent or ionic). In this case, it is a covalent molecule. You start with the carbon. You could say monocarbon, but if it is just said to be carbon it is assumed to be one. Then you take the prefix for 4 and tack it on to the beginning of the chlorine. For this, the name is carbon tetrachloride.

The Sun heats land and water, how is this related to wind and ocean currents?
Yuki888 [10]

Answer:

"The sun warms up parts of the oceans. Warm waters rise just like warm air rises. So, as the warmer ocean waters begin to rise in a particular area, the cooler ocean waters from a different area will move in to replace the warmer ocean waters, and this creates our ocean currents."

Explanation:

Hope this is helpful :)

The road map in the text shows that to convert from one unit to another, you must use the ____ as an intermediate step. ___ conv
jonny [76]

Answer:

Conversion factor;

Molar mass;

Avogadro's constant and molar mass

Explanation:

  • Firstly, an intermediate step is to define the conversion factor that will be then used in a conversion technique called dimensional analysis in order to convert from one unit to another. An example of a conversion factor would be, for example, 1 L = 1000 mL, which can be manipulated as a fraction, either \frac{1 L}{1000 mL} or \frac{1000 mL}{1 L};
  • Secondly, in order to convert mass to moles, we need to know the molar mass of a compound which has a units of g/mol (that is, it shows how many grams we have per 1 mole of substance.
  • Thirdly, Avogadro's constant, N_A = 6.022\cdot 10^{23} mol^{-1} tells us that there is N_A number of molecules or atoms in 1 mole of substance. We need two conversion factors to convert the number of molecules to a mass: firstly, we need to convert the number of molecules into the number of moles using Avogadro's constant and then we need to use the molar mass to convert the moles obtained into mass.

Anita was using steel to make rusted sculptures. After building each sculpture, she caused the steel in the sculpture to rust by
alexandr1967 [171]

Answer:

The type of liquid in the tub (salt water or vinegar)

Explanation:

<em>The manipulated independent variable in Anita's experiment is </em><em>the type of liquid in the tub. </em>

The independent variable is the controlled or manipulated variable in the course of an experiment. It can also be referred to as the 'cause' variable which has the capacity to produce 'effects' on another variable - the dependent variable.

In this case, the type of liquid the tub is filled (salt water or vinegar) will hypothetically affect the rusting period of the steel. Hence, the dependent variable is the type of liquid the tub is filled while the dependent variable would be the time it takes for the steel to get rusted.

Specify which indicator or indicators you would use for the following titrations:
Helen [10]

Answer:

1. Phenolphthalein

2. Phenolphthalein

3. Methyl orange

Explanation:

Different indicators are used by knowing the relative strength of the acid and the bases I.e whether the acid is strong or weak, so also the base.

The following answers are obtainable:

1. Phenolphthalein

We use this indicator for a weak base and a strong acid. Formic acid is a weak organic acid while sodium hydroxide is a strong base

2. Phenolphthalein

We use this indicator because we are dealing with a strong acid and a strong base. Hydrochloric acid is a strong acid while potassium hydroxide is a strong base

3. Methyl orange

This is because we are dealing with a strong acid and a weak base
