Answer 2

thank you

Answer 3

A reaction is monitored and the products are found to be a salt and water. The reactant(s) must have been?
a metal-nonmetal compound
an acid and a base
a metal and a metal-nonmetal compound
two metal-nonmetal compounds

Answer 4

acid and base

Answer 5

If approximately equal volumes of an acid and a base of equal strengths are combined, the resulting solution should have a pH of
around 7
above 7
below 7
impossible to determine

Answer 6

\[\approx7\]

Answer 7

≈7
whats that

Answer 8

around 7 sorry for late reply was browsing

Answer 9

In the following reaction, which substance is the precipitate?

(NH4)2SO4(aq) + Ba(NO3)2(aq) BaSO4(s) + 2NH4NO3(aq)

Answer 10

sorry I was browsing

Answer 11

Barium sulphate (it's the only not aq)

Answer 12

@kdday here? :)

Answer 13

so its the Ba9no302(aq)

Answer 14

\(BaSO_4\)

Answer 15

Study the following reaction carefully. What classification should this reaction have?

H2SO4 + 2NaOH Na2SO4 + 2H2O


synthesis
decomposition
single replacement
neutralization

Answer 16

neutralization
acid+base is always neutralization

Answer 17

word equation:
Sulfuric acid+Sodium hydroxide->Sodium sulfate+Water

Answer 18

okay i get it now, so When a double displacement reaction takes place, one of the products must be?

a salt
a gas
a precipitate
water

Answer 19

salt, because it's ionic :)

Answer 20

i got a 99 yay! are you good at math too? i needa tutor like you

Answer 21

yep I am now helping others at math that's why i always have late reply :)

Answer 22

send the link to me after you ask the question :)

Answer 23

He's not really tutoring, he's giving you answers and you're not learning much.

Answer 24

okay abb0t and ur point is !
after i get the awnser i research and reaad !

Answer 25

Answer 29

What is the equation of the line described below written in slope-intercept form?

the line passing through point (2, 2) and perpendicular to the line whose equation is y = x


y = x - 4
y = x + 4
y = -x + 4

Answer 30

What is the equation of the line described below written in slope-intercept form?

the line passing through point (2, 2) and perpendicular to the line whose equation is y = x


y = x - 4
y = x + 4
y = -x + 4

Answer 31

So they're perpendicular, which means that the product of the slopes is -1.

Answer 32

and the slope of the new line is therefore -1.

Answer 33

@kdday

Answer 34

substitute the coordinates into the equation :)

Answer 35

@kc_kennylau okay so is it

y = x - 4
y = x + 4
y = -x + 4
