1 lacks evidence
2 supported by evidence
3 subjective
4 objective
5 unresponsive to new information
6 continually updated
which traits are those of science?
a.2, 3, and 6
b.1, 3, and 5
c.1, 4, and 6
d.2, 4, and 6

The correct answer is option 2, 4 and 6

Explanation:

The very basic definition of pseudoscience is a form of science which exits and is excepted by mass as truth but doesn't have any logical backing. Or in other words pseudoscience concepts are more or less considered as truth which do not require any justification , thus they are universal truth and therefore are not updated and remains constant while in science all concepts are backed by logic and these logic keep on refining with more intervention into the subject.

An example of pseudoscience is horoscope - people believe it but there is no logical backing. Its concepts are also the same since its starting. There has been no refinement of its logic.

when 25.0 ml of 0.700 mol/l naoh was mixed in a calorimeter with 25.0 ml of 0.700 mol/l hcl, both initially at 20.0 °c, the temperature increased to 22.1 °c. the heat capacity of the calorimeter is 279 j/°c.

the equation for the reaction is:

naoh + hcl → nacl + h₂o

moles of hcl = 0.0250 l hcl ×

0.700

mol hcl

1 l hcl = 0.0175 mol hcl

volume of solution = (25.0 + 25.0) ml = 50.0 ml

mass of solution = 50.0 ml soln ×

1.00

ml soln

= 50.0 g soln

δt=t2-t1

= (22.1 – 20.0) °c = 2.1 °c

the heats involved are

heat from neutralization + heat to warm solution + heat to warm calorimeter = 0

q1+q2+q3=0

nδh+mcδt+cδt=0

0.0175 mol ×

δh

+ 50.0 g × 4.184 j·g⁻¹°c⁻¹ × 2.1 °c + 279 j°c⁻¹ × 2.1 °c = 0

0.0175 mol ×

δh

+ 439.32 j + 585.9 j = 0

0.0175 mol ×

δh

= -1025.22 j

δh=1025.22j0.0175 mol= -58 600 j/mol = -58.6 kj/mol

i would say b

explanation:

but i think i would need more information than that
