Brainliet- chemistry !

1. first, solve for the total amount of naoh used:
initial amount ml naoh – final amount ml naoh = total ml naoh used

50ml-30ml=20ml of naoh < (i did this)

2. next, solve for the moles of hcl in the flask using its known concentration:
ml naoh used x 1 l x molarity naoh x 1 mol hcl = mol hcl
1000 ml 1 mol naoh

3. lastly, solve for the molarity of hcl. be sure to convert the volume of hcl solution from ml to l before plugging into the equation below.
mol hcl = concentration (m) of the hcl solution
l hcl
ph=-log[h30+]
h+=-log[-0.30]
h+= -0.5228
you have to start by adding the ph, then proceeding by solving using logarithms.

1. determining the molarity of hcl in part 1:

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
