You own a fireworks company. You are out of the element sodium (Na) and need to substitute an element with similar properties before your fireworks show starts.
Chlorine (Cl), because it is in the same period as sodium, and elements in the same period have similar electron structure and similar chemical properties.
Lithium (Li), because it is in the same group as sodium, and elements in the same group have similar electron structure and similar chemical properties
Magnesium (Mg), because it only has one more proton than sodium and therefore, similar chemical properties.
Neon (Ne), because it only has one less proton than sodium and therefore, similar chemical properties

Chemical change; sugar dissolves in the tea and water due to heat being added to the water
Chemical change; sugar dissolves in the tea and water which breaks the bonds of the molecules
Sally rolled a marble down a ramp to investigate the potential energy and kinetic energy of a marble. She planned to measure the kinetic and potential energy at three different points but forgot to measure the kinetic energy at Point C.
the kinetic energy would be 0 joules at Point C
the kinetic energy at Point C would have to be 16 joules
the kinetic energy at Point C would have to be 12 joules
the kinetic energy would be 1 joule at Point C
In a chemical reaction, table sugar (sucrose) is mixed with sulfuric acid. The result of the reaction is a towering black structure of elemental carbon, water vapor, carbon dioxide, and sulfur dioxide gases.
How can conservation of matter be proved using this reaction?
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 resultant gases and structure should be weighed to show that the resultants are heavier than the products
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 energy lost can be added to the resultants and compared to the original masses.

Recipes for baked goods, such as cookies, cakes, and quick breads, tend to use softened butter because it mixes much easier with flour and sugar in batters or cookie dough than hard, cold butter or even melted butter. Softened butter is made by letting the butter sit at room temperature until it is soft to the touch. Use your knowledge to particles to explain why softened butter is better for baking.
The particles in the softened butter are moving slower and are further apart making it easier to combine with other ingredients.
The particles in softened butter are moving faster and have less attractive forces so the butter combines more easily with the other ingredients.
The particles in the softened butter are moving faster and are very close together making it easier for them to combine.
The particles in the softened butter are moving slower and have more attractive forces so the butter combines more easily with other ingredients.
