Answer:

Mass is 5560 grams

Explanation:

[tex]{ \boxed{mass = density \times volume}}[/tex]

Density is 5.56 g/L

Volume is 1 m³ = 1,000 L

Substitute the following to get mass:

[tex]mass = (5.56 \times 1000) \\ { \boxed{ \boxed{mass = 5560 \: grams}}}[/tex]

Answer:

they’re all pure substances. Carbon dioxide is not an element

Explanation:

Note down the formula below

[tex]\boxed{\sf Mass\%\;of\; element=\dfrac{Mass\:of\:the\: element}{Mass\;of\:the\: compound}\times 100}[/tex]

Mass of the compound

[tex]\\ \sf\longmapsto 32+2=34g[/tex]

Mass % of Hydrogen:-

[tex]\\ \sf\longmapsto \dfrac{2}{34}\times 100[/tex]

[tex]\\ \sf\longmapsto \dfrac{1}{17}\times 100[/tex]

[tex]\\ \sf\longmapsto 5.8\%[/tex]

Mass % of Oxygen:-

[tex]\\ \sf\longmapsto \dfrac{32}{34}\times 100[/tex]

[tex]\\ \sf\longmapsto \dfrac{16}{17}\times 100[/tex]

[tex]\\ \sf\longmapsto 94.2\%[/tex]

Answer is Gasoline

Gasoline is a fuel made from crude oil and other petroleum liquids. Gasoline is mainly used as an engine fuel in vehicles. Petroleum refineries and blending facilities produce motor gasoline for sale at retail gasoline fueling stations.

Hope my answer will help you !!

Answer:

Charge is caused by a flow of electrons, since electrons are around the nucleus they can be lost or gained by atoms. When an atom gets charged, it gains a charge, that is, it gains an electron. Since electrons are negatively charged, when an atom gains one, it also becomes negatively charged.

To solve such this we must know the concept of combustion reaction. Therefore, the elements must be contained in fossil fuels are carbon, hydrogen and oxygen.

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.

Combustion reaction is a reaction in which a substance, basically hydrocarbons burns in presence of oxygen to produce carbon dioxide and water. When fossil fuel are burned, carbon dioxide and water are produced. The elements must be contained in fossil fuels are carbon, hydrogen and oxygen.

Therefore, the elements must be contained in fossil fuels are carbon, hydrogen and oxygen.

A synthesis reaction is a chemical reaction in which two different atoms interact together to produce a different molecule or compound.

Sodium is an alkali metal with the atomic number 11. It has a +1 valence electron in its outermost shell.

Chlorine is a halogen family element with the atomic element 17. It requires an electron to complete its octet structure.

That is why the bonding reaction between them is called Electrovalent or Ionic bonding.

When 2 moles of Sodium (Na) combines with 1 mole of Chlorine (Cl), we have:

[tex]\mathbf{2 Na_{(s)} + Cl_2_{(g)} \ \to \ 2NaCl_{(s)} }[/tex]

Therefore, from the above reaction, we can conclude that there are two molecules of sodium produced when two atoms of sodium (Na) combine with one molecule of chlorine gas (Cl2).

Answer:

negative acceleration describes a decrease in velocity over time. Acceleration is an increase and zero acceleration is no change in velocity.

Explanation:

The zero calibration of the electronic balance allows to maintain the precision of one digit.

Electronic measurement equipment has a mechanism to set the zero of the measurement every time the equipment is turned on, this procedure must be carried out to eliminate:

The methods of regurgitating the zero of the balance consists of measuring the weight without masses and bringing this value to zero, in general by changing some adjustable parameter of the balance, for example magnetic field current, reference level with a beam of light.

With this calibration it will be achieved that there is always a precision digit in the readings.

With Electronic Balance Calibration it is possible to have a pressure digit
