Tony gets stung by an ant. He applies baking soda, a weak base, to the site. What acid is Tony neutralizing with the baking soda
kumpel [21]
That's good !  I never heard of that before.  (Maybe because
I've never been stung by an ant.)

When an ant bites or stings, it injects a tiny amount of 'formic acid'
into your skin.  Soon, the formic acid itches, burns, and stings, and
after a while, a little piece of skin dies and falls off.  Some people
are seriously allergic to it, and it can make them really sick.

'Acids' and 'bases' are opposites, and one can neutralize (cancel out)
the other.  Tony is putting a weak 'base' on the sting, to neutralize the
formic acid that the ant left him as a little gift.

PLEASE HELP
kykrilka [37]

Answer:

Both physical and chemical changes

Explanation:

From the definition of the law of conservation of mass, total mass of all the substances taking part in a chemical reaction is conserved and the number of atoms of each element in the reaction does not change when a new product is formed. Both physical and chemical changes follow the law since when the system is closed to all transfers of matter and energy, the mass of the system must remain constant over time, irrespective of the state.

If Tony and Tanya both run at the same speed and in the same direction and they both run for the same amount of time, what can y
Marina86 [1]

Answer: They travel equal distances

Explanation:

Distance is amount of space covered from one point to another. It is measured in metres. Distance = speed x time taken

In this case,

- Since Tony and Tanya both run at the same speed: let speed = b

- Also, both run for the same amount of time: let time = c

Therefore, distance covered by Tony and Tanya = speed x time taken

Distance = b x c

Distance = bc (i.e Tony travelled a distance of bc, so also Tanya)
