Question 14 In a chemical reaction, table sugar (sucrose) is mixed with sulfuric acid. The result of the reaction is a lowering black structure of elemental carbon, water vapor, carbon dioxide, and sulfur dioxide gases.
How can conservation of matter be proved using this reaction?
А The masses of the resultant gases and structure should be weighed to show that the resultants are lighter than the products.
The masses of the sugar, sulfuric acid, and glassware should be recorded before the experiment, then the resulting reactant masses should be compared with the original masses.
The masses of the sugar, sulfuric acid, and glassware should be recorded before the experiment, then the energy lost can be added to the resultants and compared to the original masses.
The masses of the resultant gases and structure should be welghed to show that the resultants are heavier than the products.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

your answer is c) plasma

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
